HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 655, 388, 980, 580 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 655, 388, 980, 580 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 655, 388, 980, 580 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 655, 388, 980, 580 is 1.

HCF(655, 388, 980, 580) = 1

Highest Common Factor of 655,388,980,580 using Euclid's algorithm

Highest Common Factor of 655,388,980,580 is 1

Step 1: Since 655 > 388, we apply the division lemma to 655 and 388, to get

655 = 388 x 1 + 267

Step 2: Since the reminder 388 ≠ 0, we apply division lemma to 267 and 388, to get

388 = 267 x 1 + 121

Step 3: We consider the new divisor 267 and the new remainder 121, and apply the division lemma to get

267 = 121 x 2 + 25

We consider the new divisor 121 and the new remainder 25,and apply the division lemma to get

121 = 25 x 4 + 21

We consider the new divisor 25 and the new remainder 21,and apply the division lemma to get

25 = 21 x 1 + 4

We consider the new divisor 21 and the new remainder 4,and apply the division lemma to get

21 = 4 x 5 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 655 and 388 is 1

Notice that 1 = HCF(4,1) = HCF(21,4) = HCF(25,21) = HCF(121,25) = HCF(267,121) = HCF(388,267) = HCF(655,388) .

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

Step 1: Since 980 > 1, we apply the division lemma to 980 and 1, to get

980 = 1 x 980 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 980 is 1

Notice that 1 = HCF(980,1) .

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

Step 1: Since 580 > 1, we apply the division lemma to 580 and 1, to get

580 = 1 x 580 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 580 is 1

Notice that 1 = HCF(580,1) .
