HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 637, 851, 512, 904 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 637, 851, 512, 904 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 637, 851, 512, 904 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 637, 851, 512, 904 is 1.

HCF(637, 851, 512, 904) = 1

Highest Common Factor of 637,851,512,904 using Euclid's algorithm

Highest Common Factor of 637,851,512,904 is 1

Step 1: Since 851 > 637, we apply the division lemma to 851 and 637, to get

851 = 637 x 1 + 214

Step 2: Since the reminder 637 ≠ 0, we apply division lemma to 214 and 637, to get

637 = 214 x 2 + 209

Step 3: We consider the new divisor 214 and the new remainder 209, and apply the division lemma to get

214 = 209 x 1 + 5

We consider the new divisor 209 and the new remainder 5,and apply the division lemma to get

209 = 5 x 41 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 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 637 and 851 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(209,5) = HCF(214,209) = HCF(637,214) = HCF(851,637) .


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

Step 1: Since 512 > 1, we apply the division lemma to 512 and 1, to get

512 = 1 x 512 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 512 is 1

Notice that 1 = HCF(512,1) .


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

Step 1: Since 904 > 1, we apply the division lemma to 904 and 1, to get

904 = 1 x 904 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 904 is 1

Notice that 1 = HCF(904,1) .
