HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 660, 389, 413, 126 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 660, 389, 413, 126 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 660, 389, 413, 126 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 660, 389, 413, 126 is 1.

HCF(660, 389, 413, 126) = 1

Highest common factor (HCF) of 660, 389, 413, 126 is 1.

Highest Common Factor of 660,389,413,126 using Euclid's algorithm

Highest Common Factor of 660,389,413,126 is 1

Step 1: Since 660 > 389, we apply the division lemma to 660 and 389, to get

660 = 389 x 1 + 271

Step 2: Since the reminder 389 ≠ 0, we apply division lemma to 271 and 389, to get

389 = 271 x 1 + 118

Step 3: We consider the new divisor 271 and the new remainder 118, and apply the division lemma to get

271 = 118 x 2 + 35

We consider the new divisor 118 and the new remainder 35,and apply the division lemma to get

118 = 35 x 3 + 13

We consider the new divisor 35 and the new remainder 13,and apply the division lemma to get

35 = 13 x 2 + 9

We consider the new divisor 13 and the new remainder 9,and apply the division lemma to get

13 = 9 x 1 + 4

We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get

9 = 4 x 2 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 660 and 389 is 1

Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(13,9) = HCF(35,13) = HCF(118,35) = HCF(271,118) = HCF(389,271) = HCF(660,389) .

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

Step 1: Since 413 > 1, we apply the division lemma to 413 and 1, to get

413 = 1 x 413 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 413 is 1

Notice that 1 = HCF(413,1) .

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

Step 1: Since 126 > 1, we apply the division lemma to 126 and 1, to get

126 = 1 x 126 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 126 is 1

Notice that 1 = HCF(126,1) .
