HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 644, 756, 601 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 644, 756, 601 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 644, 756, 601 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 644, 756, 601 is 1.

HCF(644, 756, 601) = 1

HCF of 644, 756, 601 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 644, 756, 601 is 1.

Highest Common Factor of 644,756,601 using Euclid's algorithm

Highest Common Factor of 644,756,601 is 1

Step 1: Since 756 > 644, we apply the division lemma to 756 and 644, to get

756 = 644 x 1 + 112

Step 2: Since the reminder 644 ≠ 0, we apply division lemma to 112 and 644, to get

644 = 112 x 5 + 84

Step 3: We consider the new divisor 112 and the new remainder 84, and apply the division lemma to get

112 = 84 x 1 + 28

We consider the new divisor 84 and the new remainder 28, and apply the division lemma to get

84 = 28 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 28, the HCF of 644 and 756 is 28

Notice that 28 = HCF(84,28) = HCF(112,84) = HCF(644,112) = HCF(756,644) .

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

Step 1: Since 601 > 28, we apply the division lemma to 601 and 28, to get

601 = 28 x 21 + 13

Step 2: Since the reminder 28 ≠ 0, we apply division lemma to 13 and 28, to get

28 = 13 x 2 + 2

Step 3: We consider the new divisor 13 and the new remainder 2, and apply the division lemma to get

13 = 2 x 6 + 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 28 and 601 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(28,13) = HCF(601,28) .
