HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 912, 718, 455 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 912, 718, 455 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 912, 718, 455 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 912, 718, 455 is 1.

HCF(912, 718, 455) = 1

HCF of 912, 718, 455 using Euclid's algorithm

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

Highest common factor (HCF) of 912, 718, 455 is 1.

Highest Common Factor of 912,718,455 using Euclid's algorithm

Highest Common Factor of 912,718,455 is 1

Step 1: Since 912 > 718, we apply the division lemma to 912 and 718, to get

912 = 718 x 1 + 194

Step 2: Since the reminder 718 ≠ 0, we apply division lemma to 194 and 718, to get

718 = 194 x 3 + 136

Step 3: We consider the new divisor 194 and the new remainder 136, and apply the division lemma to get

194 = 136 x 1 + 58

We consider the new divisor 136 and the new remainder 58,and apply the division lemma to get

136 = 58 x 2 + 20

We consider the new divisor 58 and the new remainder 20,and apply the division lemma to get

58 = 20 x 2 + 18

We consider the new divisor 20 and the new remainder 18,and apply the division lemma to get

20 = 18 x 1 + 2

We consider the new divisor 18 and the new remainder 2,and apply the division lemma to get

18 = 2 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 912 and 718 is 2

Notice that 2 = HCF(18,2) = HCF(20,18) = HCF(58,20) = HCF(136,58) = HCF(194,136) = HCF(718,194) = HCF(912,718) .


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

Step 1: Since 455 > 2, we apply the division lemma to 455 and 2, to get

455 = 2 x 227 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 455 is 1

Notice that 1 = HCF(2,1) = HCF(455,2) .
