HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 754, 427, 778 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 754, 427, 778 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 754, 427, 778 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 754, 427, 778 is 1.

HCF(754, 427, 778) = 1

HCF of 754, 427, 778 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 754, 427, 778 is 1.

Highest Common Factor of 754,427,778 using Euclid's algorithm

Highest Common Factor of 754,427,778 is 1

Step 1: Since 754 > 427, we apply the division lemma to 754 and 427, to get

754 = 427 x 1 + 327

Step 2: Since the reminder 427 ≠ 0, we apply division lemma to 327 and 427, to get

427 = 327 x 1 + 100

Step 3: We consider the new divisor 327 and the new remainder 100, and apply the division lemma to get

327 = 100 x 3 + 27

We consider the new divisor 100 and the new remainder 27,and apply the division lemma to get

100 = 27 x 3 + 19

We consider the new divisor 27 and the new remainder 19,and apply the division lemma to get

27 = 19 x 1 + 8

We consider the new divisor 19 and the new remainder 8,and apply the division lemma to get

19 = 8 x 2 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 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 754 and 427 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(19,8) = HCF(27,19) = HCF(100,27) = HCF(327,100) = HCF(427,327) = HCF(754,427) .

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

Step 1: Since 778 > 1, we apply the division lemma to 778 and 1, to get

778 = 1 x 778 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 778 is 1

Notice that 1 = HCF(778,1) .
