HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 617, 629, 903, 90 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 617, 629, 903, 90 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 617, 629, 903, 90 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 617, 629, 903, 90 is 1.

HCF(617, 629, 903, 90) = 1

Highest common factor (HCF) of 617, 629, 903, 90 is 1.

Highest Common Factor of 617,629,903,90 using Euclid's algorithm

Highest Common Factor of 617,629,903,90 is 1

Step 1: Since 629 > 617, we apply the division lemma to 629 and 617, to get

629 = 617 x 1 + 12

Step 2: Since the reminder 617 ≠ 0, we apply division lemma to 12 and 617, to get

617 = 12 x 51 + 5

Step 3: We consider the new divisor 12 and the new remainder 5, and apply the division lemma to get

12 = 5 x 2 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 617 and 629 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(617,12) = HCF(629,617) .

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

Step 1: Since 903 > 1, we apply the division lemma to 903 and 1, to get

903 = 1 x 903 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 903 is 1

Notice that 1 = HCF(903,1) .

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

Step 1: Since 90 > 1, we apply the division lemma to 90 and 1, to get

90 = 1 x 90 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 90 is 1

Notice that 1 = HCF(90,1) .
