HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 64, 65, 934, 661 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 64, 65, 934, 661 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 64, 65, 934, 661 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 64, 65, 934, 661 is 1.

HCF(64, 65, 934, 661) = 1

HCF of 64, 65, 934, 661 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 64, 65, 934, 661 is 1.

Highest Common Factor of 64,65,934,661 using Euclid's algorithm

Highest Common Factor of 64,65,934,661 is 1

Step 1: Since 65 > 64, we apply the division lemma to 65 and 64, to get

65 = 64 x 1 + 1

Step 2: Since the reminder 64 ≠ 0, we apply division lemma to 1 and 64, to get

64 = 1 x 64 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 64 and 65 is 1

Notice that 1 = HCF(64,1) = HCF(65,64) .


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

Step 1: Since 934 > 1, we apply the division lemma to 934 and 1, to get

934 = 1 x 934 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 934 is 1

Notice that 1 = HCF(934,1) .


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

Step 1: Since 661 > 1, we apply the division lemma to 661 and 1, to get

661 = 1 x 661 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 661 is 1

Notice that 1 = HCF(661,1) .
