HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 645, 887, 507 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 645, 887, 507 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, 887, 507 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, 887, 507 is 1.

HCF(645, 887, 507) = 1

HCF of 645, 887, 507 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, 887, 507 is 1.

Highest Common Factor of 645,887,507 using Euclid's algorithm

Highest Common Factor of 645,887,507 is 1

Step 1: Since 887 > 645, we apply the division lemma to 887 and 645, to get

887 = 645 x 1 + 242

Step 2: Since the reminder 645 ≠ 0, we apply division lemma to 242 and 645, to get

645 = 242 x 2 + 161

Step 3: We consider the new divisor 242 and the new remainder 161, and apply the division lemma to get

242 = 161 x 1 + 81

We consider the new divisor 161 and the new remainder 81,and apply the division lemma to get

161 = 81 x 1 + 80

We consider the new divisor 81 and the new remainder 80,and apply the division lemma to get

81 = 80 x 1 + 1

We consider the new divisor 80 and the new remainder 1,and apply the division lemma to get

80 = 1 x 80 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 645 and 887 is 1

Notice that 1 = HCF(80,1) = HCF(81,80) = HCF(161,81) = HCF(242,161) = HCF(645,242) = HCF(887,645) .

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

Step 1: Since 507 > 1, we apply the division lemma to 507 and 1, to get

507 = 1 x 507 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 507 is 1

Notice that 1 = HCF(507,1) .
