HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 611, 502, 142 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 611, 502, 142 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 611, 502, 142 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 611, 502, 142 is 1.

HCF(611, 502, 142) = 1

Highest common factor (HCF) of 611, 502, 142 is 1.

Highest Common Factor of 611,502,142 using Euclid's algorithm

Highest Common Factor of 611,502,142 is 1

Step 1: Since 611 > 502, we apply the division lemma to 611 and 502, to get

611 = 502 x 1 + 109

Step 2: Since the reminder 502 ≠ 0, we apply division lemma to 109 and 502, to get

502 = 109 x 4 + 66

Step 3: We consider the new divisor 109 and the new remainder 66, and apply the division lemma to get

109 = 66 x 1 + 43

We consider the new divisor 66 and the new remainder 43,and apply the division lemma to get

66 = 43 x 1 + 23

We consider the new divisor 43 and the new remainder 23,and apply the division lemma to get

43 = 23 x 1 + 20

We consider the new divisor 23 and the new remainder 20,and apply the division lemma to get

23 = 20 x 1 + 3

We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get

20 = 3 x 6 + 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 611 and 502 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(23,20) = HCF(43,23) = HCF(66,43) = HCF(109,66) = HCF(502,109) = HCF(611,502) .

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

Step 1: Since 142 > 1, we apply the division lemma to 142 and 1, to get

142 = 1 x 142 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 142 is 1

Notice that 1 = HCF(142,1) .
