Highest Common Factor of 54, 6, 78 using Euclid's algorithm

HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 54, 6, 78 i.e. 6 the largest integer that leaves a remainder zero for all numbers.

HCF of 54, 6, 78 is 6 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 54, 6, 78 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 54, 6, 78 is 6.

HCF(54, 6, 78) = 6

HCF of 54, 6, 78 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 54, 6, 78 is 6.

Highest Common Factor of 54,6,78 using Euclid's algorithm

Step 1: Since 54 > 6, we apply the division lemma to 54 and 6, to get

54 = 6 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 54 and 6 is 6

Notice that 6 = HCF(54,6) .


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

Step 1: Since 78 > 6, we apply the division lemma to 78 and 6, to get

78 = 6 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 6 and 78 is 6

Notice that 6 = HCF(78,6) .
