HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 24, 123, 102 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 24, 123, 102 is 3 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 24, 123, 102 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 24, 123, 102 is 3.

HCF(24, 123, 102) = 3

HCF of 24, 123, 102 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 24, 123, 102 is 3.

Highest Common Factor of 24,123,102 using Euclid's algorithm

Highest Common Factor of 24,123,102 is 3

Step 1: Since 123 > 24, we apply the division lemma to 123 and 24, to get

123 = 24 x 5 + 3

Step 2: Since the reminder 24 ≠ 0, we apply division lemma to 3 and 24, to get

24 = 3 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 24 and 123 is 3

Notice that 3 = HCF(24,3) = HCF(123,24) .


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

Step 1: Since 102 > 3, we apply the division lemma to 102 and 3, to get

102 = 3 x 34 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 102 is 3

Notice that 3 = HCF(102,3) .
