HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 397, 853, 712 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 397, 853, 712 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 397, 853, 712 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 397, 853, 712 is 1.

HCF(397, 853, 712) = 1

Highest common factor (HCF) of 397, 853, 712 is 1.

Highest Common Factor of 397,853,712 using Euclid's algorithm

Highest Common Factor of 397,853,712 is 1

Step 1: Since 853 > 397, we apply the division lemma to 853 and 397, to get

853 = 397 x 2 + 59

Step 2: Since the reminder 397 ≠ 0, we apply division lemma to 59 and 397, to get

397 = 59 x 6 + 43

Step 3: We consider the new divisor 59 and the new remainder 43, and apply the division lemma to get

59 = 43 x 1 + 16

We consider the new divisor 43 and the new remainder 16,and apply the division lemma to get

43 = 16 x 2 + 11

We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get

16 = 11 x 1 + 5

We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get

11 = 5 x 2 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 397 and 853 is 1

Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(43,16) = HCF(59,43) = HCF(397,59) = HCF(853,397) .

We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

Step 1: Since 712 > 1, we apply the division lemma to 712 and 1, to get

712 = 1 x 712 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 712 is 1

Notice that 1 = HCF(712,1) .
