HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 930 i.e. 30 the largest integer that leaves a remainder zero for all numbers.

HCF of 870, 930 is 30 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 870, 930 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 870, 930 is 30.

HCF(870, 930) = 30

Highest common factor (HCF) of 870, 930 is 30.

Highest Common Factor of 870,930 using Euclid's algorithm

Highest Common Factor of 870,930 is 30

Step 1: Since 930 > 870, we apply the division lemma to 930 and 870, to get

930 = 870 x 1 + 60

Step 2: Since the reminder 870 ≠ 0, we apply division lemma to 60 and 870, to get

870 = 60 x 14 + 30

Step 3: We consider the new divisor 60 and the new remainder 30, and apply the division lemma to get

60 = 30 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 30, the HCF of 870 and 930 is 30

Notice that 30 = HCF(60,30) = HCF(870,60) = HCF(930,870) .
