HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 242, 151, 100 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 242, 151, 100 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 242, 151, 100 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 242, 151, 100 is 1.

HCF(242, 151, 100) = 1

HCF of 242, 151, 100 using Euclid's algorithm

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

Highest common factor (HCF) of 242, 151, 100 is 1.

Highest Common Factor of 242,151,100 using Euclid's algorithm

Highest Common Factor of 242,151,100 is 1

Step 1: Since 242 > 151, we apply the division lemma to 242 and 151, to get

242 = 151 x 1 + 91

Step 2: Since the reminder 151 ≠ 0, we apply division lemma to 91 and 151, to get

151 = 91 x 1 + 60

Step 3: We consider the new divisor 91 and the new remainder 60, and apply the division lemma to get

91 = 60 x 1 + 31

We consider the new divisor 60 and the new remainder 31,and apply the division lemma to get

60 = 31 x 1 + 29

We consider the new divisor 31 and the new remainder 29,and apply the division lemma to get

31 = 29 x 1 + 2

We consider the new divisor 29 and the new remainder 2,and apply the division lemma to get

29 = 2 x 14 + 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 242 and 151 is 1

Notice that 1 = HCF(2,1) = HCF(29,2) = HCF(31,29) = HCF(60,31) = HCF(91,60) = HCF(151,91) = HCF(242,151) .

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

Step 1: Since 100 > 1, we apply the division lemma to 100 and 1, to get

100 = 1 x 100 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 100 is 1

Notice that 1 = HCF(100,1) .
