HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 635, 915, 635 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 635, 915, 635 is 5 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 635, 915, 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 635, 915, 635 is 5.

HCF(635, 915, 635) = 5

Highest common factor (HCF) of 635, 915, 635 is 5.

Highest Common Factor of 635,915,635 using Euclid's algorithm

Highest Common Factor of 635,915,635 is 5

Step 1: Since 915 > 635, we apply the division lemma to 915 and 635, to get

915 = 635 x 1 + 280

Step 2: Since the reminder 635 ≠ 0, we apply division lemma to 280 and 635, to get

635 = 280 x 2 + 75

Step 3: We consider the new divisor 280 and the new remainder 75, and apply the division lemma to get

280 = 75 x 3 + 55

We consider the new divisor 75 and the new remainder 55,and apply the division lemma to get

75 = 55 x 1 + 20

We consider the new divisor 55 and the new remainder 20,and apply the division lemma to get

55 = 20 x 2 + 15

We consider the new divisor 20 and the new remainder 15,and apply the division lemma to get

20 = 15 x 1 + 5

We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get

15 = 5 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 635 and 915 is 5

Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(55,20) = HCF(75,55) = HCF(280,75) = HCF(635,280) = HCF(915,635) .


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

Step 1: Since 635 > 5, we apply the division lemma to 635 and 5, to get

635 = 5 x 127 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 635 is 5

Notice that 5 = HCF(635,5) .
