HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 640, 998, 60 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 640, 998, 60 is 2 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 640, 998, 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 640, 998, 60 is 2.

HCF(640, 998, 60) = 2

HCF of 640, 998, 60 using Euclid's algorithm

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

Highest common factor (HCF) of 640, 998, 60 is 2.

Highest Common Factor of 640,998,60 using Euclid's algorithm

Highest Common Factor of 640,998,60 is 2

Step 1: Since 998 > 640, we apply the division lemma to 998 and 640, to get

998 = 640 x 1 + 358

Step 2: Since the reminder 640 ≠ 0, we apply division lemma to 358 and 640, to get

640 = 358 x 1 + 282

Step 3: We consider the new divisor 358 and the new remainder 282, and apply the division lemma to get

358 = 282 x 1 + 76

We consider the new divisor 282 and the new remainder 76,and apply the division lemma to get

282 = 76 x 3 + 54

We consider the new divisor 76 and the new remainder 54,and apply the division lemma to get

76 = 54 x 1 + 22

We consider the new divisor 54 and the new remainder 22,and apply the division lemma to get

54 = 22 x 2 + 10

We consider the new divisor 22 and the new remainder 10,and apply the division lemma to get

22 = 10 x 2 + 2

We consider the new divisor 10 and the new remainder 2,and apply the division lemma to get

10 = 2 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 640 and 998 is 2

Notice that 2 = HCF(10,2) = HCF(22,10) = HCF(54,22) = HCF(76,54) = HCF(282,76) = HCF(358,282) = HCF(640,358) = HCF(998,640) .


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

Step 1: Since 60 > 2, we apply the division lemma to 60 and 2, to get

60 = 2 x 30 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 60 is 2

Notice that 2 = HCF(60,2) .
