HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 7628, 990 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 7628, 990 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 7628, 990 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 7628, 990 is 2.

HCF(7628, 990) = 2

Highest Common Factor of 7628,990 using Euclid's algorithm

Highest Common Factor of 7628,990 is 2

Step 1: Since 7628 > 990, we apply the division lemma to 7628 and 990, to get

7628 = 990 x 7 + 698

Step 2: Since the reminder 990 ≠ 0, we apply division lemma to 698 and 990, to get

990 = 698 x 1 + 292

Step 3: We consider the new divisor 698 and the new remainder 292, and apply the division lemma to get

698 = 292 x 2 + 114

We consider the new divisor 292 and the new remainder 114,and apply the division lemma to get

292 = 114 x 2 + 64

We consider the new divisor 114 and the new remainder 64,and apply the division lemma to get

114 = 64 x 1 + 50

We consider the new divisor 64 and the new remainder 50,and apply the division lemma to get

64 = 50 x 1 + 14

We consider the new divisor 50 and the new remainder 14,and apply the division lemma to get

50 = 14 x 3 + 8

We consider the new divisor 14 and the new remainder 8,and apply the division lemma to get

14 = 8 x 1 + 6

We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get

8 = 6 x 1 + 2

We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get

6 = 2 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 7628 and 990 is 2

Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(14,8) = HCF(50,14) = HCF(64,50) = HCF(114,64) = HCF(292,114) = HCF(698,292) = HCF(990,698) = HCF(7628,990) .
