HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 73, 26, 91, 101 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 73, 26, 91, 101 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 73, 26, 91, 101 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 73, 26, 91, 101 is 1.

HCF(73, 26, 91, 101) = 1

## HCF of 73, 26, 91, 101 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 73, 26, 91, 101 is 1. ### Highest Common Factor of 73,26,91,101 is 1

Step 1: Since 73 > 26, we apply the division lemma to 73 and 26, to get

73 = 26 x 2 + 21

Step 2: Since the reminder 26 ≠ 0, we apply division lemma to 21 and 26, to get

26 = 21 x 1 + 5

Step 3: We consider the new divisor 21 and the new remainder 5, and apply the division lemma to get

21 = 5 x 4 + 1

We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 73 and 26 is 1

Notice that 1 = HCF(5,1) = HCF(21,5) = HCF(26,21) = HCF(73,26) .

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

Step 1: Since 91 > 1, we apply the division lemma to 91 and 1, to get

91 = 1 x 91 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 91 is 1

Notice that 1 = HCF(91,1) .

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

Step 1: Since 101 > 1, we apply the division lemma to 101 and 1, to get

101 = 1 x 101 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 101 is 1

Notice that 1 = HCF(101,1) .
