HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 911, 990, 22 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 911, 990, 22 is 1 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 911, 990, 22 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 911, 990, 22 is 1.

HCF(911, 990, 22) = 1

Highest common factor (HCF) of 911, 990, 22 is 1.

Highest Common Factor of 911,990,22 using Euclid's algorithm

Highest Common Factor of 911,990,22 is 1

Step 1: Since 990 > 911, we apply the division lemma to 990 and 911, to get

990 = 911 x 1 + 79

Step 2: Since the reminder 911 ≠ 0, we apply division lemma to 79 and 911, to get

911 = 79 x 11 + 42

Step 3: We consider the new divisor 79 and the new remainder 42, and apply the division lemma to get

79 = 42 x 1 + 37

We consider the new divisor 42 and the new remainder 37,and apply the division lemma to get

42 = 37 x 1 + 5

We consider the new divisor 37 and the new remainder 5,and apply the division lemma to get

37 = 5 x 7 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 911 and 990 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(37,5) = HCF(42,37) = HCF(79,42) = HCF(911,79) = HCF(990,911) .


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

Step 1: Since 22 > 1, we apply the division lemma to 22 and 1, to get

22 = 1 x 22 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 22 is 1

Notice that 1 = HCF(22,1) .
