HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 868, 774, 975 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 868, 774, 975 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 868, 774, 975 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 868, 774, 975 is 1.

HCF(868, 774, 975) = 1

HCF of 868, 774, 975 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 868, 774, 975 is 1.

Highest Common Factor of 868,774,975 using Euclid's algorithm

Highest Common Factor of 868,774,975 is 1

Step 1: Since 868 > 774, we apply the division lemma to 868 and 774, to get

868 = 774 x 1 + 94

Step 2: Since the reminder 774 ≠ 0, we apply division lemma to 94 and 774, to get

774 = 94 x 8 + 22

Step 3: We consider the new divisor 94 and the new remainder 22, and apply the division lemma to get

94 = 22 x 4 + 6

We consider the new divisor 22 and the new remainder 6,and apply the division lemma to get

22 = 6 x 3 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 868 and 774 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(22,6) = HCF(94,22) = HCF(774,94) = HCF(868,774) .

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

Step 1: Since 975 > 2, we apply the division lemma to 975 and 2, to get

975 = 2 x 487 + 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 975 is 1

Notice that 1 = HCF(2,1) = HCF(975,2) .
