HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 615, 546, 114, 640 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 615, 546, 114, 640 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 615, 546, 114, 640 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 615, 546, 114, 640 is 1.

HCF(615, 546, 114, 640) = 1

HCF of 615, 546, 114, 640 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 615, 546, 114, 640 is 1.

Highest Common Factor of 615,546,114,640 using Euclid's algorithm

Highest Common Factor of 615,546,114,640 is 1

Step 1: Since 615 > 546, we apply the division lemma to 615 and 546, to get

615 = 546 x 1 + 69

Step 2: Since the reminder 546 ≠ 0, we apply division lemma to 69 and 546, to get

546 = 69 x 7 + 63

Step 3: We consider the new divisor 69 and the new remainder 63, and apply the division lemma to get

69 = 63 x 1 + 6

We consider the new divisor 63 and the new remainder 6,and apply the division lemma to get

63 = 6 x 10 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 615 and 546 is 3

Notice that 3 = HCF(6,3) = HCF(63,6) = HCF(69,63) = HCF(546,69) = HCF(615,546) .


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

Step 1: Since 114 > 3, we apply the division lemma to 114 and 3, to get

114 = 3 x 38 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 114 is 3

Notice that 3 = HCF(114,3) .


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

Step 1: Since 640 > 3, we apply the division lemma to 640 and 3, to get

640 = 3 x 213 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 640 is 1

Notice that 1 = HCF(3,1) = HCF(640,3) .
