HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 671, 925, 428 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 671, 925, 428 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 671, 925, 428 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 671, 925, 428 is 1.

HCF(671, 925, 428) = 1

Highest common factor (HCF) of 671, 925, 428 is 1.

Highest Common Factor of 671,925,428 using Euclid's algorithm

Highest Common Factor of 671,925,428 is 1

Step 1: Since 925 > 671, we apply the division lemma to 925 and 671, to get

925 = 671 x 1 + 254

Step 2: Since the reminder 671 ≠ 0, we apply division lemma to 254 and 671, to get

671 = 254 x 2 + 163

Step 3: We consider the new divisor 254 and the new remainder 163, and apply the division lemma to get

254 = 163 x 1 + 91

We consider the new divisor 163 and the new remainder 91,and apply the division lemma to get

163 = 91 x 1 + 72

We consider the new divisor 91 and the new remainder 72,and apply the division lemma to get

91 = 72 x 1 + 19

We consider the new divisor 72 and the new remainder 19,and apply the division lemma to get

72 = 19 x 3 + 15

We consider the new divisor 19 and the new remainder 15,and apply the division lemma to get

19 = 15 x 1 + 4

We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get

15 = 4 x 3 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 671 and 925 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(19,15) = HCF(72,19) = HCF(91,72) = HCF(163,91) = HCF(254,163) = HCF(671,254) = HCF(925,671) .

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

Step 1: Since 428 > 1, we apply the division lemma to 428 and 1, to get

428 = 1 x 428 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 428 is 1

Notice that 1 = HCF(428,1) .
