HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 198, 955 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 198, 955 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 198, 955 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, 955 is 1.

HCF(198, 955) = 1

Highest Common Factor of 198,955 using Euclid's algorithm

Highest Common Factor of 198,955 is 1

Step 1: Since 955 > 198, we apply the division lemma to 955 and 198, to get

955 = 198 x 4 + 163

Step 2: Since the reminder 198 ≠ 0, we apply division lemma to 163 and 198, to get

198 = 163 x 1 + 35

Step 3: We consider the new divisor 163 and the new remainder 35, and apply the division lemma to get

163 = 35 x 4 + 23

We consider the new divisor 35 and the new remainder 23,and apply the division lemma to get

35 = 23 x 1 + 12

We consider the new divisor 23 and the new remainder 12,and apply the division lemma to get

23 = 12 x 1 + 11

We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get

12 = 11 x 1 + 1

We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 198 and 955 is 1

Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(23,12) = HCF(35,23) = HCF(163,35) = HCF(198,163) = HCF(955,198) .
