HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 642, 583, 11 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 642, 583, 11 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 642, 583, 11 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 642, 583, 11 is 1.

HCF(642, 583, 11) = 1

Highest common factor (HCF) of 642, 583, 11 is 1.

Highest Common Factor of 642,583,11 using Euclid's algorithm

Highest Common Factor of 642,583,11 is 1

Step 1: Since 642 > 583, we apply the division lemma to 642 and 583, to get

642 = 583 x 1 + 59

Step 2: Since the reminder 583 ≠ 0, we apply division lemma to 59 and 583, to get

583 = 59 x 9 + 52

Step 3: We consider the new divisor 59 and the new remainder 52, and apply the division lemma to get

59 = 52 x 1 + 7

We consider the new divisor 52 and the new remainder 7,and apply the division lemma to get

52 = 7 x 7 + 3

We consider the new divisor 7 and the new remainder 3,and apply the division lemma to get

7 = 3 x 2 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 642 and 583 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(52,7) = HCF(59,52) = HCF(583,59) = HCF(642,583) .

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

Step 1: Since 11 > 1, we apply the division lemma to 11 and 1, to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 11 is 1

Notice that 1 = HCF(11,1) .
