HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 947, 694 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 947, 694 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 947, 694 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 947, 694 is 1.

HCF(947, 694) = 1

Highest common factor (HCF) of 947, 694 is 1.

Highest Common Factor of 947,694 using Euclid's algorithm

Highest Common Factor of 947,694 is 1

Step 1: Since 947 > 694, we apply the division lemma to 947 and 694, to get

947 = 694 x 1 + 253

Step 2: Since the reminder 694 ≠ 0, we apply division lemma to 253 and 694, to get

694 = 253 x 2 + 188

Step 3: We consider the new divisor 253 and the new remainder 188, and apply the division lemma to get

253 = 188 x 1 + 65

We consider the new divisor 188 and the new remainder 65,and apply the division lemma to get

188 = 65 x 2 + 58

We consider the new divisor 65 and the new remainder 58,and apply the division lemma to get

65 = 58 x 1 + 7

We consider the new divisor 58 and the new remainder 7,and apply the division lemma to get

58 = 7 x 8 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 947 and 694 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(58,7) = HCF(65,58) = HCF(188,65) = HCF(253,188) = HCF(694,253) = HCF(947,694) .
