HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 128, 72, 969, 327 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 128, 72, 969, 327 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 128, 72, 969, 327 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 128, 72, 969, 327 is 1.

HCF(128, 72, 969, 327) = 1

Highest common factor (HCF) of 128, 72, 969, 327 is 1.

Highest Common Factor of 128,72,969,327 using Euclid's algorithm

Highest Common Factor of 128,72,969,327 is 1

Step 1: Since 128 > 72, we apply the division lemma to 128 and 72, to get

128 = 72 x 1 + 56

Step 2: Since the reminder 72 ≠ 0, we apply division lemma to 56 and 72, to get

72 = 56 x 1 + 16

Step 3: We consider the new divisor 56 and the new remainder 16, and apply the division lemma to get

56 = 16 x 3 + 8

We consider the new divisor 16 and the new remainder 8, and apply the division lemma to get

16 = 8 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 128 and 72 is 8

Notice that 8 = HCF(16,8) = HCF(56,16) = HCF(72,56) = HCF(128,72) .


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

Step 1: Since 969 > 8, we apply the division lemma to 969 and 8, to get

969 = 8 x 121 + 1

Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 1 and 8, to get

8 = 1 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 8 and 969 is 1

Notice that 1 = HCF(8,1) = HCF(969,8) .


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

Step 1: Since 327 > 1, we apply the division lemma to 327 and 1, to get

327 = 1 x 327 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 327 is 1

Notice that 1 = HCF(327,1) .
