HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 645, 199, 910 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 645, 199, 910 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 645, 199, 910 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 645, 199, 910 is 1.

HCF(645, 199, 910) = 1

HCF of 645, 199, 910 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 645, 199, 910 is 1.

Highest Common Factor of 645,199,910 using Euclid's algorithm

Highest Common Factor of 645,199,910 is 1

Step 1: Since 645 > 199, we apply the division lemma to 645 and 199, to get

645 = 199 x 3 + 48

Step 2: Since the reminder 199 ≠ 0, we apply division lemma to 48 and 199, to get

199 = 48 x 4 + 7

Step 3: We consider the new divisor 48 and the new remainder 7, and apply the division lemma to get

48 = 7 x 6 + 6

We consider the new divisor 7 and the new remainder 6,and apply the division lemma to get

7 = 6 x 1 + 1

We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get

6 = 1 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 645 and 199 is 1

Notice that 1 = HCF(6,1) = HCF(7,6) = HCF(48,7) = HCF(199,48) = HCF(645,199) .


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

Step 1: Since 910 > 1, we apply the division lemma to 910 and 1, to get

910 = 1 x 910 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 910 is 1

Notice that 1 = HCF(910,1) .
