HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 911, 390, 36 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 911, 390, 36 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, 390, 36 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, 390, 36 is 1.

HCF(911, 390, 36) = 1

Highest Common Factor of 911,390,36 using Euclid's algorithm

Highest Common Factor of 911,390,36 is 1

Step 1: Since 911 > 390, we apply the division lemma to 911 and 390, to get

911 = 390 x 2 + 131

Step 2: Since the reminder 390 ≠ 0, we apply division lemma to 131 and 390, to get

390 = 131 x 2 + 128

Step 3: We consider the new divisor 131 and the new remainder 128, and apply the division lemma to get

131 = 128 x 1 + 3

We consider the new divisor 128 and the new remainder 3,and apply the division lemma to get

128 = 3 x 42 + 2

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

3 = 2 x 1 + 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 390 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(128,3) = HCF(131,128) = HCF(390,131) = HCF(911,390) .

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

Step 1: Since 36 > 1, we apply the division lemma to 36 and 1, to get

36 = 1 x 36 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 36 is 1

Notice that 1 = HCF(36,1) .
