HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 198, 726, 158 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 198, 726, 158 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 198, 726, 158 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 198, 726, 158 is 2.

HCF(198, 726, 158) = 2

Highest common factor (HCF) of 198, 726, 158 is 2.

Highest Common Factor of 198,726,158 using Euclid's algorithm

Highest Common Factor of 198,726,158 is 2

Step 1: Since 726 > 198, we apply the division lemma to 726 and 198, to get

726 = 198 x 3 + 132

Step 2: Since the reminder 198 ≠ 0, we apply division lemma to 132 and 198, to get

198 = 132 x 1 + 66

Step 3: We consider the new divisor 132 and the new remainder 66, and apply the division lemma to get

132 = 66 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 66, the HCF of 198 and 726 is 66

Notice that 66 = HCF(132,66) = HCF(198,132) = HCF(726,198) .


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

Step 1: Since 158 > 66, we apply the division lemma to 158 and 66, to get

158 = 66 x 2 + 26

Step 2: Since the reminder 66 ≠ 0, we apply division lemma to 26 and 66, to get

66 = 26 x 2 + 14

Step 3: We consider the new divisor 26 and the new remainder 14, and apply the division lemma to get

26 = 14 x 1 + 12

We consider the new divisor 14 and the new remainder 12,and apply the division lemma to get

14 = 12 x 1 + 2

We consider the new divisor 12 and the new remainder 2,and apply the division lemma to get

12 = 2 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 66 and 158 is 2

Notice that 2 = HCF(12,2) = HCF(14,12) = HCF(26,14) = HCF(66,26) = HCF(158,66) .
