HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 508, 872, 635 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 508, 872, 635 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 508, 872, 635 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 508, 872, 635 is 1.

HCF(508, 872, 635) = 1

Highest Common Factor of 508,872,635 using Euclid's algorithm

Highest Common Factor of 508,872,635 is 1

Step 1: Since 872 > 508, we apply the division lemma to 872 and 508, to get

872 = 508 x 1 + 364

Step 2: Since the reminder 508 ≠ 0, we apply division lemma to 364 and 508, to get

508 = 364 x 1 + 144

Step 3: We consider the new divisor 364 and the new remainder 144, and apply the division lemma to get

364 = 144 x 2 + 76

We consider the new divisor 144 and the new remainder 76,and apply the division lemma to get

144 = 76 x 1 + 68

We consider the new divisor 76 and the new remainder 68,and apply the division lemma to get

76 = 68 x 1 + 8

We consider the new divisor 68 and the new remainder 8,and apply the division lemma to get

68 = 8 x 8 + 4

We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get

8 = 4 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 508 and 872 is 4

Notice that 4 = HCF(8,4) = HCF(68,8) = HCF(76,68) = HCF(144,76) = HCF(364,144) = HCF(508,364) = HCF(872,508) .

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

Step 1: Since 635 > 4, we apply the division lemma to 635 and 4, to get

635 = 4 x 158 + 3

Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get

4 = 3 x 1 + 1

Step 3: 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 4 and 635 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(635,4) .
