HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 930, 142 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 930, 142 is 2 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 930, 142 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 930, 142 is 2.

HCF(930, 142) = 2

Highest common factor (HCF) of 930, 142 is 2.

Highest Common Factor of 930,142 using Euclid's algorithm

Highest Common Factor of 930,142 is 2

Step 1: Since 930 > 142, we apply the division lemma to 930 and 142, to get

930 = 142 x 6 + 78

Step 2: Since the reminder 142 ≠ 0, we apply division lemma to 78 and 142, to get

142 = 78 x 1 + 64

Step 3: We consider the new divisor 78 and the new remainder 64, and apply the division lemma to get

78 = 64 x 1 + 14

We consider the new divisor 64 and the new remainder 14,and apply the division lemma to get

64 = 14 x 4 + 8

We consider the new divisor 14 and the new remainder 8,and apply the division lemma to get

14 = 8 x 1 + 6

We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get

8 = 6 x 1 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 930 and 142 is 2

Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(14,8) = HCF(64,14) = HCF(78,64) = HCF(142,78) = HCF(930,142) .
