HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 974, 544, 23 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 974, 544, 23 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 974, 544, 23 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 974, 544, 23 is 1.

HCF(974, 544, 23) = 1

Highest Common Factor of 974,544,23 using Euclid's algorithm

Highest Common Factor of 974,544,23 is 1

Step 1: Since 974 > 544, we apply the division lemma to 974 and 544, to get

974 = 544 x 1 + 430

Step 2: Since the reminder 544 ≠ 0, we apply division lemma to 430 and 544, to get

544 = 430 x 1 + 114

Step 3: We consider the new divisor 430 and the new remainder 114, and apply the division lemma to get

430 = 114 x 3 + 88

We consider the new divisor 114 and the new remainder 88,and apply the division lemma to get

114 = 88 x 1 + 26

We consider the new divisor 88 and the new remainder 26,and apply the division lemma to get

88 = 26 x 3 + 10

We consider the new divisor 26 and the new remainder 10,and apply the division lemma to get

26 = 10 x 2 + 6

We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get

10 = 6 x 1 + 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 974 and 544 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(26,10) = HCF(88,26) = HCF(114,88) = HCF(430,114) = HCF(544,430) = HCF(974,544) .

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

Step 1: Since 23 > 2, we apply the division lemma to 23 and 2, to get

23 = 2 x 11 + 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 23 is 1

Notice that 1 = HCF(2,1) = HCF(23,2) .
