HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 942, 278, 812 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 942, 278, 812 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 942, 278, 812 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 942, 278, 812 is 2.

HCF(942, 278, 812) = 2

Highest common factor (HCF) of 942, 278, 812 is 2.

Highest Common Factor of 942,278,812 using Euclid's algorithm

Highest Common Factor of 942,278,812 is 2

Step 1: Since 942 > 278, we apply the division lemma to 942 and 278, to get

942 = 278 x 3 + 108

Step 2: Since the reminder 278 ≠ 0, we apply division lemma to 108 and 278, to get

278 = 108 x 2 + 62

Step 3: We consider the new divisor 108 and the new remainder 62, and apply the division lemma to get

108 = 62 x 1 + 46

We consider the new divisor 62 and the new remainder 46,and apply the division lemma to get

62 = 46 x 1 + 16

We consider the new divisor 46 and the new remainder 16,and apply the division lemma to get

46 = 16 x 2 + 14

We consider the new divisor 16 and the new remainder 14,and apply the division lemma to get

16 = 14 x 1 + 2

We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get

14 = 2 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 942 and 278 is 2

Notice that 2 = HCF(14,2) = HCF(16,14) = HCF(46,16) = HCF(62,46) = HCF(108,62) = HCF(278,108) = HCF(942,278) .

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

Step 1: Since 812 > 2, we apply the division lemma to 812 and 2, to get

812 = 2 x 406 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 812 is 2

Notice that 2 = HCF(812,2) .
