HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 990, 11020 i.e. 10 the largest integer that leaves a remainder zero for all numbers.

HCF of 990, 11020 is 10 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 990, 11020 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 990, 11020 is 10.

HCF(990, 11020) = 10

Highest Common Factor of 990,11020 using Euclid's algorithm

Highest Common Factor of 990,11020 is 10

Step 1: Since 11020 > 990, we apply the division lemma to 11020 and 990, to get

11020 = 990 x 11 + 130

Step 2: Since the reminder 990 ≠ 0, we apply division lemma to 130 and 990, to get

990 = 130 x 7 + 80

Step 3: We consider the new divisor 130 and the new remainder 80, and apply the division lemma to get

130 = 80 x 1 + 50

We consider the new divisor 80 and the new remainder 50,and apply the division lemma to get

80 = 50 x 1 + 30

We consider the new divisor 50 and the new remainder 30,and apply the division lemma to get

50 = 30 x 1 + 20

We consider the new divisor 30 and the new remainder 20,and apply the division lemma to get

30 = 20 x 1 + 10

We consider the new divisor 20 and the new remainder 10,and apply the division lemma to get

20 = 10 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 10, the HCF of 990 and 11020 is 10

Notice that 10 = HCF(20,10) = HCF(30,20) = HCF(50,30) = HCF(80,50) = HCF(130,80) = HCF(990,130) = HCF(11020,990) .
