HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 772, 312 i.e. 4 the largest integer that leaves a remainder zero for all numbers.

HCF of 772, 312 is 4 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 772, 312 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 772, 312 is 4.

HCF(772, 312) = 4

HCF of 772, 312 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 772, 312 is 4.

Highest Common Factor of 772,312 using Euclid's algorithm

Highest Common Factor of 772,312 is 4

Step 1: Since 772 > 312, we apply the division lemma to 772 and 312, to get

772 = 312 x 2 + 148

Step 2: Since the reminder 312 ≠ 0, we apply division lemma to 148 and 312, to get

312 = 148 x 2 + 16

Step 3: We consider the new divisor 148 and the new remainder 16, and apply the division lemma to get

148 = 16 x 9 + 4

We consider the new divisor 16 and the new remainder 4, and apply the division lemma to get

16 = 4 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 772 and 312 is 4

Notice that 4 = HCF(16,4) = HCF(148,16) = HCF(312,148) = HCF(772,312) .
