HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 242, 940 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 242, 940 is 2 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, 940 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, 940 is 2.

HCF(242, 940) = 2

Highest Common Factor of 242,940 using Euclid's algorithm

Highest Common Factor of 242,940 is 2

Step 1: Since 940 > 242, we apply the division lemma to 940 and 242, to get

940 = 242 x 3 + 214

Step 2: Since the reminder 242 ≠ 0, we apply division lemma to 214 and 242, to get

242 = 214 x 1 + 28

Step 3: We consider the new divisor 214 and the new remainder 28, and apply the division lemma to get

214 = 28 x 7 + 18

We consider the new divisor 28 and the new remainder 18,and apply the division lemma to get

28 = 18 x 1 + 10

We consider the new divisor 18 and the new remainder 10,and apply the division lemma to get

18 = 10 x 1 + 8

We consider the new divisor 10 and the new remainder 8,and apply the division lemma to get

10 = 8 x 1 + 2

We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get

8 = 2 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 242 and 940 is 2

Notice that 2 = HCF(8,2) = HCF(10,8) = HCF(18,10) = HCF(28,18) = HCF(214,28) = HCF(242,214) = HCF(940,242) .
