HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 242, 121, 292 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 242, 121, 292 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, 121, 292 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, 121, 292 is 1.

HCF(242, 121, 292) = 1

Highest common factor (HCF) of 242, 121, 292 is 1.

Highest Common Factor of 242,121,292 using Euclid's algorithm

Highest Common Factor of 242,121,292 is 1

Step 1: Since 242 > 121, we apply the division lemma to 242 and 121, to get

242 = 121 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 121, the HCF of 242 and 121 is 121

Notice that 121 = HCF(242,121) .

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

Step 1: Since 292 > 121, we apply the division lemma to 292 and 121, to get

292 = 121 x 2 + 50

Step 2: Since the reminder 121 ≠ 0, we apply division lemma to 50 and 121, to get

121 = 50 x 2 + 21

Step 3: We consider the new divisor 50 and the new remainder 21, and apply the division lemma to get

50 = 21 x 2 + 8

We consider the new divisor 21 and the new remainder 8,and apply the division lemma to get

21 = 8 x 2 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

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

5 = 3 x 1 + 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 121 and 292 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(21,8) = HCF(50,21) = HCF(121,50) = HCF(292,121) .
