HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 702, 955 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 702, 955 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 702, 955 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 702, 955 is 1.

HCF(702, 955) = 1

Highest common factor (HCF) of 702, 955 is 1.

Highest Common Factor of 702,955 using Euclid's algorithm

Highest Common Factor of 702,955 is 1

Step 1: Since 955 > 702, we apply the division lemma to 955 and 702, to get

955 = 702 x 1 + 253

Step 2: Since the reminder 702 ≠ 0, we apply division lemma to 253 and 702, to get

702 = 253 x 2 + 196

Step 3: We consider the new divisor 253 and the new remainder 196, and apply the division lemma to get

253 = 196 x 1 + 57

We consider the new divisor 196 and the new remainder 57,and apply the division lemma to get

196 = 57 x 3 + 25

We consider the new divisor 57 and the new remainder 25,and apply the division lemma to get

57 = 25 x 2 + 7

We consider the new divisor 25 and the new remainder 7,and apply the division lemma to get

25 = 7 x 3 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 702 and 955 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(25,7) = HCF(57,25) = HCF(196,57) = HCF(253,196) = HCF(702,253) = HCF(955,702) .
