HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 312, 660 i.e. 12 the largest integer that leaves a remainder zero for all numbers.

HCF of 312, 660 is 12 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 312, 660 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 312, 660 is 12.

HCF(312, 660) = 12

HCF of 312, 660 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 312, 660 is 12.

Highest Common Factor of 312,660 using Euclid's algorithm

Highest Common Factor of 312,660 is 12

Step 1: Since 660 > 312, we apply the division lemma to 660 and 312, to get

660 = 312 x 2 + 36

Step 2: Since the reminder 312 ≠ 0, we apply division lemma to 36 and 312, to get

312 = 36 x 8 + 24

Step 3: We consider the new divisor 36 and the new remainder 24, and apply the division lemma to get

36 = 24 x 1 + 12

We consider the new divisor 24 and the new remainder 12, and apply the division lemma to get

24 = 12 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 312 and 660 is 12

Notice that 12 = HCF(24,12) = HCF(36,24) = HCF(312,36) = HCF(660,312) .
