HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 391, 227, 60 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 391, 227, 60 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 391, 227, 60 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 391, 227, 60 is 1.

HCF(391, 227, 60) = 1

Highest common factor (HCF) of 391, 227, 60 is 1.

Highest Common Factor of 391,227,60 using Euclid's algorithm

Highest Common Factor of 391,227,60 is 1

Step 1: Since 391 > 227, we apply the division lemma to 391 and 227, to get

391 = 227 x 1 + 164

Step 2: Since the reminder 227 ≠ 0, we apply division lemma to 164 and 227, to get

227 = 164 x 1 + 63

Step 3: We consider the new divisor 164 and the new remainder 63, and apply the division lemma to get

164 = 63 x 2 + 38

We consider the new divisor 63 and the new remainder 38,and apply the division lemma to get

63 = 38 x 1 + 25

We consider the new divisor 38 and the new remainder 25,and apply the division lemma to get

38 = 25 x 1 + 13

We consider the new divisor 25 and the new remainder 13,and apply the division lemma to get

25 = 13 x 1 + 12

We consider the new divisor 13 and the new remainder 12,and apply the division lemma to get

13 = 12 x 1 + 1

We consider the new divisor 12 and the new remainder 1,and apply the division lemma to get

12 = 1 x 12 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 391 and 227 is 1

Notice that 1 = HCF(12,1) = HCF(13,12) = HCF(25,13) = HCF(38,25) = HCF(63,38) = HCF(164,63) = HCF(227,164) = HCF(391,227) .

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

Step 1: Since 60 > 1, we apply the division lemma to 60 and 1, to get

60 = 1 x 60 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 60 is 1

Notice that 1 = HCF(60,1) .
