HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 270, 480, 679 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 270, 480, 679 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 270, 480, 679 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 270, 480, 679 is 1.

HCF(270, 480, 679) = 1

Highest common factor (HCF) of 270, 480, 679 is 1.

Highest Common Factor of 270,480,679 using Euclid's algorithm

Highest Common Factor of 270,480,679 is 1

Step 1: Since 480 > 270, we apply the division lemma to 480 and 270, to get

480 = 270 x 1 + 210

Step 2: Since the reminder 270 ≠ 0, we apply division lemma to 210 and 270, to get

270 = 210 x 1 + 60

Step 3: We consider the new divisor 210 and the new remainder 60, and apply the division lemma to get

210 = 60 x 3 + 30

We consider the new divisor 60 and the new remainder 30, and apply the division lemma to get

60 = 30 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 30, the HCF of 270 and 480 is 30

Notice that 30 = HCF(60,30) = HCF(210,60) = HCF(270,210) = HCF(480,270) .


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

Step 1: Since 679 > 30, we apply the division lemma to 679 and 30, to get

679 = 30 x 22 + 19

Step 2: Since the reminder 30 ≠ 0, we apply division lemma to 19 and 30, to get

30 = 19 x 1 + 11

Step 3: We consider the new divisor 19 and the new remainder 11, and apply the division lemma to get

19 = 11 x 1 + 8

We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get

11 = 8 x 1 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 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 30 and 679 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(19,11) = HCF(30,19) = HCF(679,30) .
