HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 183, 646, 101, 639 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 183, 646, 101, 639 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 183, 646, 101, 639 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 183, 646, 101, 639 is 1.

HCF(183, 646, 101, 639) = 1

Highest Common Factor of 183,646,101,639 using Euclid's algorithm

Highest Common Factor of 183,646,101,639 is 1

Step 1: Since 646 > 183, we apply the division lemma to 646 and 183, to get

646 = 183 x 3 + 97

Step 2: Since the reminder 183 ≠ 0, we apply division lemma to 97 and 183, to get

183 = 97 x 1 + 86

Step 3: We consider the new divisor 97 and the new remainder 86, and apply the division lemma to get

97 = 86 x 1 + 11

We consider the new divisor 86 and the new remainder 11,and apply the division lemma to get

86 = 11 x 7 + 9

We consider the new divisor 11 and the new remainder 9,and apply the division lemma to get

11 = 9 x 1 + 2

We consider the new divisor 9 and the new remainder 2,and apply the division lemma to get

9 = 2 x 4 + 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 183 and 646 is 1

Notice that 1 = HCF(2,1) = HCF(9,2) = HCF(11,9) = HCF(86,11) = HCF(97,86) = HCF(183,97) = HCF(646,183) .


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

Step 1: Since 101 > 1, we apply the division lemma to 101 and 1, to get

101 = 1 x 101 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 101 is 1

Notice that 1 = HCF(101,1) .


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

Step 1: Since 639 > 1, we apply the division lemma to 639 and 1, to get

639 = 1 x 639 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 639 is 1

Notice that 1 = HCF(639,1) .
