HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 78, 976, 757 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 78, 976, 757 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 78, 976, 757 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 78, 976, 757 is 1.

HCF(78, 976, 757) = 1

HCF of 78, 976, 757 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 78, 976, 757 is 1.

Highest Common Factor of 78,976,757 using Euclid's algorithm

Highest Common Factor of 78,976,757 is 1

Step 1: Since 976 > 78, we apply the division lemma to 976 and 78, to get

976 = 78 x 12 + 40

Step 2: Since the reminder 78 ≠ 0, we apply division lemma to 40 and 78, to get

78 = 40 x 1 + 38

Step 3: We consider the new divisor 40 and the new remainder 38, and apply the division lemma to get

40 = 38 x 1 + 2

We consider the new divisor 38 and the new remainder 2, and apply the division lemma to get

38 = 2 x 19 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 78 and 976 is 2

Notice that 2 = HCF(38,2) = HCF(40,38) = HCF(78,40) = HCF(976,78) .


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

Step 1: Since 757 > 2, we apply the division lemma to 757 and 2, to get

757 = 2 x 378 + 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 757 is 1

Notice that 1 = HCF(2,1) = HCF(757,2) .
