WebPrime factorisation of 30 = (2 × 3 × 5) Prime factorisation of 105 = (3 × 5 × 7) Hence, the HCF of 30 and 105 is 3 × 5 = 15. HCF (30, 105) = 15. HCF of 30 and 105 by Long Division Method. The divisor that we receive when the remainder becomes 0 after executing long division repeatedly is HCF of 30 and 105. No further division can be done. Calculate GCF, GCD and HCFof a set of two or more numbers and see the work using factorization. Enter 2 or more whole numbers separated by commas or spaces. The Greatest Common Factor Calculator solution also works as a solution for finding: 1. Greatest common factor (GCF) 2. Greatest common denominator … See more The greatest common factor (GCF or GCD or HCF) of a set of whole numbers is the largest positive integer that divides evenly into all numbers with zero remainder. For example, for the set … See more Any non zero whole number times 0 equals 0 so it is true that every non zero whole number is a factor of 0. k × 0 = 0 so, 0 ÷ k = 0 for any whole number k. For example, 5 × 0 = 0 so it is true that 0 ÷ 5 = 0. In this example, 5 … See more There are several ways to find the greatest common factor of numbers. The most efficient method you use depends on how many numbers you … See more
