HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 318, 444, 221 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 318, 444, 221 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 318, 444, 221 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 318, 444, 221 is 1.

HCF(318, 444, 221) = 1

HCF of 318, 444, 221 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 318, 444, 221 is 1.

Highest Common Factor of 318,444,221 using Euclid's algorithm

Highest Common Factor of 318,444,221 is 1

Step 1: Since 444 > 318, we apply the division lemma to 444 and 318, to get

444 = 318 x 1 + 126

Step 2: Since the reminder 318 ≠ 0, we apply division lemma to 126 and 318, to get

318 = 126 x 2 + 66

Step 3: We consider the new divisor 126 and the new remainder 66, and apply the division lemma to get

126 = 66 x 1 + 60

We consider the new divisor 66 and the new remainder 60,and apply the division lemma to get

66 = 60 x 1 + 6

We consider the new divisor 60 and the new remainder 6,and apply the division lemma to get

60 = 6 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 318 and 444 is 6

Notice that 6 = HCF(60,6) = HCF(66,60) = HCF(126,66) = HCF(318,126) = HCF(444,318) .


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

Step 1: Since 221 > 6, we apply the division lemma to 221 and 6, to get

221 = 6 x 36 + 5

Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 5 and 6, to get

6 = 5 x 1 + 1

Step 3: 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 6 and 221 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(221,6) .
