HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 744, 607, 842 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 744, 607, 842 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 744, 607, 842 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 744, 607, 842 is 1.

HCF(744, 607, 842) = 1

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

HCF of:

Highest common factor (HCF) of 744, 607, 842 is 1.

Highest Common Factor of 744,607,842 using Euclid's algorithm

Highest Common Factor of 744,607,842 is 1

Step 1: Since 744 > 607, we apply the division lemma to 744 and 607, to get

744 = 607 x 1 + 137

Step 2: Since the reminder 607 ≠ 0, we apply division lemma to 137 and 607, to get

607 = 137 x 4 + 59

Step 3: We consider the new divisor 137 and the new remainder 59, and apply the division lemma to get

137 = 59 x 2 + 19

We consider the new divisor 59 and the new remainder 19,and apply the division lemma to get

59 = 19 x 3 + 2

We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get

19 = 2 x 9 + 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 744 and 607 is 1

Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(59,19) = HCF(137,59) = HCF(607,137) = HCF(744,607) .

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

Step 1: Since 842 > 1, we apply the division lemma to 842 and 1, to get

842 = 1 x 842 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 842 is 1

Notice that 1 = HCF(842,1) .
