HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 970, 97403 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 970, 97403 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 970, 97403 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 970, 97403 is 1.

HCF(970, 97403) = 1

Highest Common Factor of 970,97403 using Euclid's algorithm

Highest Common Factor of 970,97403 is 1

Step 1: Since 97403 > 970, we apply the division lemma to 97403 and 970, to get

97403 = 970 x 100 + 403

Step 2: Since the reminder 970 ≠ 0, we apply division lemma to 403 and 970, to get

970 = 403 x 2 + 164

Step 3: We consider the new divisor 403 and the new remainder 164, and apply the division lemma to get

403 = 164 x 2 + 75

We consider the new divisor 164 and the new remainder 75,and apply the division lemma to get

164 = 75 x 2 + 14

We consider the new divisor 75 and the new remainder 14,and apply the division lemma to get

75 = 14 x 5 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 970 and 97403 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(75,14) = HCF(164,75) = HCF(403,164) = HCF(970,403) = HCF(97403,970) .
