HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 157, 50998 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 157, 50998 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 157, 50998 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 157, 50998 is 1.

HCF(157, 50998) = 1

Highest common factor (HCF) of 157, 50998 is 1.

Highest Common Factor of 157,50998 using Euclid's algorithm

Highest Common Factor of 157,50998 is 1

Step 1: Since 50998 > 157, we apply the division lemma to 50998 and 157, to get

50998 = 157 x 324 + 130

Step 2: Since the reminder 157 ≠ 0, we apply division lemma to 130 and 157, to get

157 = 130 x 1 + 27

Step 3: We consider the new divisor 130 and the new remainder 27, and apply the division lemma to get

130 = 27 x 4 + 22

We consider the new divisor 27 and the new remainder 22,and apply the division lemma to get

27 = 22 x 1 + 5

We consider the new divisor 22 and the new remainder 5,and apply the division lemma to get

22 = 5 x 4 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 157 and 50998 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(22,5) = HCF(27,22) = HCF(130,27) = HCF(157,130) = HCF(50998,157) .
