HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 195, 722, 36 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 195, 722, 36 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, 722, 36 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, 722, 36 is 1.

HCF(195, 722, 36) = 1

Highest common factor (HCF) of 195, 722, 36 is 1.

Highest Common Factor of 195,722,36 using Euclid's algorithm

Highest Common Factor of 195,722,36 is 1

Step 1: Since 722 > 195, we apply the division lemma to 722 and 195, to get

722 = 195 x 3 + 137

Step 2: Since the reminder 195 ≠ 0, we apply division lemma to 137 and 195, to get

195 = 137 x 1 + 58

Step 3: We consider the new divisor 137 and the new remainder 58, and apply the division lemma to get

137 = 58 x 2 + 21

We consider the new divisor 58 and the new remainder 21,and apply the division lemma to get

58 = 21 x 2 + 16

We consider the new divisor 21 and the new remainder 16,and apply the division lemma to get

21 = 16 x 1 + 5

We consider the new divisor 16 and the new remainder 5,and apply the division lemma to get

16 = 5 x 3 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 195 and 722 is 1

Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(21,16) = HCF(58,21) = HCF(137,58) = HCF(195,137) = HCF(722,195) .

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

Step 1: Since 36 > 1, we apply the division lemma to 36 and 1, to get

36 = 1 x 36 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 36 is 1

Notice that 1 = HCF(36,1) .
