HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 647, 475 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 647, 475 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 647, 475 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 647, 475 is 1.

HCF(647, 475) = 1

Highest common factor (HCF) of 647, 475 is 1.

Highest Common Factor of 647,475 using Euclid's algorithm

Highest Common Factor of 647,475 is 1

Step 1: Since 647 > 475, we apply the division lemma to 647 and 475, to get

647 = 475 x 1 + 172

Step 2: Since the reminder 475 ≠ 0, we apply division lemma to 172 and 475, to get

475 = 172 x 2 + 131

Step 3: We consider the new divisor 172 and the new remainder 131, and apply the division lemma to get

172 = 131 x 1 + 41

We consider the new divisor 131 and the new remainder 41,and apply the division lemma to get

131 = 41 x 3 + 8

We consider the new divisor 41 and the new remainder 8,and apply the division lemma to get

41 = 8 x 5 + 1

We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get

8 = 1 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 647 and 475 is 1

Notice that 1 = HCF(8,1) = HCF(41,8) = HCF(131,41) = HCF(172,131) = HCF(475,172) = HCF(647,475) .
