HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 812, 373 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 812, 373 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 812, 373 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 812, 373 is 1.

HCF(812, 373) = 1

Highest common factor (HCF) of 812, 373 is 1.

Highest Common Factor of 812,373 using Euclid's algorithm

Highest Common Factor of 812,373 is 1

Step 1: Since 812 > 373, we apply the division lemma to 812 and 373, to get

812 = 373 x 2 + 66

Step 2: Since the reminder 373 ≠ 0, we apply division lemma to 66 and 373, to get

373 = 66 x 5 + 43

Step 3: We consider the new divisor 66 and the new remainder 43, and apply the division lemma to get

66 = 43 x 1 + 23

We consider the new divisor 43 and the new remainder 23,and apply the division lemma to get

43 = 23 x 1 + 20

We consider the new divisor 23 and the new remainder 20,and apply the division lemma to get

23 = 20 x 1 + 3

We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get

20 = 3 x 6 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 812 and 373 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(23,20) = HCF(43,23) = HCF(66,43) = HCF(373,66) = HCF(812,373) .
