HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 561, 7187 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 561, 7187 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 561, 7187 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 561, 7187 is 1.

HCF(561, 7187) = 1

Highest common factor (HCF) of 561, 7187 is 1.

Highest Common Factor of 561,7187 using Euclid's algorithm

Highest Common Factor of 561,7187 is 1

Step 1: Since 7187 > 561, we apply the division lemma to 7187 and 561, to get

7187 = 561 x 12 + 455

Step 2: Since the reminder 561 ≠ 0, we apply division lemma to 455 and 561, to get

561 = 455 x 1 + 106

Step 3: We consider the new divisor 455 and the new remainder 106, and apply the division lemma to get

455 = 106 x 4 + 31

We consider the new divisor 106 and the new remainder 31,and apply the division lemma to get

106 = 31 x 3 + 13

We consider the new divisor 31 and the new remainder 13,and apply the division lemma to get

31 = 13 x 2 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

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

3 = 2 x 1 + 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 561 and 7187 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(31,13) = HCF(106,31) = HCF(455,106) = HCF(561,455) = HCF(7187,561) .
