HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 28, 14, 942 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 28, 14, 942 is 2 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 28, 14, 942 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 28, 14, 942 is 2.

HCF(28, 14, 942) = 2

HCF of 28, 14, 942 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 28, 14, 942 is 2.

Highest Common Factor of 28,14,942 using Euclid's algorithm

Highest Common Factor of 28,14,942 is 2

Step 1: Since 28 > 14, we apply the division lemma to 28 and 14, to get

28 = 14 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 28 and 14 is 14

Notice that 14 = HCF(28,14) .


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

Step 1: Since 942 > 14, we apply the division lemma to 942 and 14, to get

942 = 14 x 67 + 4

Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 4 and 14, to get

14 = 4 x 3 + 2

Step 3: We consider the new divisor 4 and the new remainder 2, and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 14 and 942 is 2

Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(942,14) .
