HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 857, 507 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 857, 507 is 1 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 857, 507 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 857, 507 is 1.

HCF(857, 507) = 1

Highest common factor (HCF) of 857, 507 is 1.

Highest Common Factor of 857,507 using Euclid's algorithm

Highest Common Factor of 857,507 is 1

Step 1: Since 857 > 507, we apply the division lemma to 857 and 507, to get

857 = 507 x 1 + 350

Step 2: Since the reminder 507 ≠ 0, we apply division lemma to 350 and 507, to get

507 = 350 x 1 + 157

Step 3: We consider the new divisor 350 and the new remainder 157, and apply the division lemma to get

350 = 157 x 2 + 36

We consider the new divisor 157 and the new remainder 36,and apply the division lemma to get

157 = 36 x 4 + 13

We consider the new divisor 36 and the new remainder 13,and apply the division lemma to get

36 = 13 x 2 + 10

We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get

13 = 10 x 1 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 857 and 507 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(36,13) = HCF(157,36) = HCF(350,157) = HCF(507,350) = HCF(857,507) .
