HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 769, 938, 644 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 769, 938, 644 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 769, 938, 644 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 769, 938, 644 is 1.

HCF(769, 938, 644) = 1

HCF of 769, 938, 644 using Euclid's algorithm

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

Highest common factor (HCF) of 769, 938, 644 is 1.

Highest Common Factor of 769,938,644 using Euclid's algorithm

Highest Common Factor of 769,938,644 is 1

Step 1: Since 938 > 769, we apply the division lemma to 938 and 769, to get

938 = 769 x 1 + 169

Step 2: Since the reminder 769 ≠ 0, we apply division lemma to 169 and 769, to get

769 = 169 x 4 + 93

Step 3: We consider the new divisor 169 and the new remainder 93, and apply the division lemma to get

169 = 93 x 1 + 76

We consider the new divisor 93 and the new remainder 76,and apply the division lemma to get

93 = 76 x 1 + 17

We consider the new divisor 76 and the new remainder 17,and apply the division lemma to get

76 = 17 x 4 + 8

We consider the new divisor 17 and the new remainder 8,and apply the division lemma to get

17 = 8 x 2 + 1

We consider the new divisor 8 and the new remainder 1,and apply the division lemma to get

8 = 1 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 769 and 938 is 1

Notice that 1 = HCF(8,1) = HCF(17,8) = HCF(76,17) = HCF(93,76) = HCF(169,93) = HCF(769,169) = HCF(938,769) .

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

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

644 = 1 x 644 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 644 is 1

Notice that 1 = HCF(644,1) .
