HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 220, 363, 473 i.e. 11 the largest integer that leaves a remainder zero for all numbers.

HCF of 220, 363, 473 is 11 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 220, 363, 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 220, 363, 473 is 11.

HCF(220, 363, 473) = 11

HCF of 220, 363, 473 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

Highest common factor (HCF) of 220, 363, 473 is 11.

Highest Common Factor of 220,363,473 using Euclid's algorithm

Highest Common Factor of 220,363,473 is 11

Step 1: Since 363 > 220, we apply the division lemma to 363 and 220, to get

363 = 220 x 1 + 143

Step 2: Since the reminder 220 ≠ 0, we apply division lemma to 143 and 220, to get

220 = 143 x 1 + 77

Step 3: We consider the new divisor 143 and the new remainder 77, and apply the division lemma to get

143 = 77 x 1 + 66

We consider the new divisor 77 and the new remainder 66,and apply the division lemma to get

77 = 66 x 1 + 11

We consider the new divisor 66 and the new remainder 11,and apply the division lemma to get

66 = 11 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 220 and 363 is 11

Notice that 11 = HCF(66,11) = HCF(77,66) = HCF(143,77) = HCF(220,143) = HCF(363,220) .


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

Step 1: Since 473 > 11, we apply the division lemma to 473 and 11, to get

473 = 11 x 43 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 11 and 473 is 11

Notice that 11 = HCF(473,11) .
