HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 195, 500, 202 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 195, 500, 202 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 195, 500, 202 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 195, 500, 202 is 1.

HCF(195, 500, 202) = 1

Highest Common Factor of 195,500,202 using Euclid's algorithm

Highest Common Factor of 195,500,202 is 1

Step 1: Since 500 > 195, we apply the division lemma to 500 and 195, to get

500 = 195 x 2 + 110

Step 2: Since the reminder 195 ≠ 0, we apply division lemma to 110 and 195, to get

195 = 110 x 1 + 85

Step 3: We consider the new divisor 110 and the new remainder 85, and apply the division lemma to get

110 = 85 x 1 + 25

We consider the new divisor 85 and the new remainder 25,and apply the division lemma to get

85 = 25 x 3 + 10

We consider the new divisor 25 and the new remainder 10,and apply the division lemma to get

25 = 10 x 2 + 5

We consider the new divisor 10 and the new remainder 5,and apply the division lemma to get

10 = 5 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 195 and 500 is 5

Notice that 5 = HCF(10,5) = HCF(25,10) = HCF(85,25) = HCF(110,85) = HCF(195,110) = HCF(500,195) .

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

Step 1: Since 202 > 5, we apply the division lemma to 202 and 5, to get

202 = 5 x 40 + 2

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 2 and 5, to get

5 = 2 x 2 + 1

Step 3: 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 5 and 202 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(202,5) .
