HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 363, 202, 473 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 363, 202, 473 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 363, 202, 473 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 363, 202, 473 is 1.

HCF(363, 202, 473) = 1

Highest common factor (HCF) of 363, 202, 473 is 1.

Highest Common Factor of 363,202,473 using Euclid's algorithm

Highest Common Factor of 363,202,473 is 1

Step 1: Since 363 > 202, we apply the division lemma to 363 and 202, to get

363 = 202 x 1 + 161

Step 2: Since the reminder 202 ≠ 0, we apply division lemma to 161 and 202, to get

202 = 161 x 1 + 41

Step 3: We consider the new divisor 161 and the new remainder 41, and apply the division lemma to get

161 = 41 x 3 + 38

We consider the new divisor 41 and the new remainder 38,and apply the division lemma to get

41 = 38 x 1 + 3

We consider the new divisor 38 and the new remainder 3,and apply the division lemma to get

38 = 3 x 12 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 363 and 202 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(38,3) = HCF(41,38) = HCF(161,41) = HCF(202,161) = HCF(363,202) .

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

Step 1: Since 473 > 1, we apply the division lemma to 473 and 1, to get

473 = 1 x 473 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 473 is 1

Notice that 1 = HCF(473,1) .
