HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 77, 438, 964 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 77, 438, 964 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 77, 438, 964 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 77, 438, 964 is 1.

HCF(77, 438, 964) = 1

HCF of 77, 438, 964 using Euclid's algorithm

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

Highest common factor (HCF) of 77, 438, 964 is 1.

Highest Common Factor of 77,438,964 using Euclid's algorithm

Highest Common Factor of 77,438,964 is 1

Step 1: Since 438 > 77, we apply the division lemma to 438 and 77, to get

438 = 77 x 5 + 53

Step 2: Since the reminder 77 ≠ 0, we apply division lemma to 53 and 77, to get

77 = 53 x 1 + 24

Step 3: We consider the new divisor 53 and the new remainder 24, and apply the division lemma to get

53 = 24 x 2 + 5

We consider the new divisor 24 and the new remainder 5,and apply the division lemma to get

24 = 5 x 4 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 77 and 438 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(24,5) = HCF(53,24) = HCF(77,53) = HCF(438,77) .

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

Step 1: Since 964 > 1, we apply the division lemma to 964 and 1, to get

964 = 1 x 964 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 964 is 1

Notice that 1 = HCF(964,1) .
