HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 501, 994, 660, 77 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 501, 994, 660, 77 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 501, 994, 660, 77 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 501, 994, 660, 77 is 1.

HCF(501, 994, 660, 77) = 1

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

HCF of:

Highest common factor (HCF) of 501, 994, 660, 77 is 1.

Highest Common Factor of 501,994,660,77 using Euclid's algorithm

Highest Common Factor of 501,994,660,77 is 1

Step 1: Since 994 > 501, we apply the division lemma to 994 and 501, to get

994 = 501 x 1 + 493

Step 2: Since the reminder 501 ≠ 0, we apply division lemma to 493 and 501, to get

501 = 493 x 1 + 8

Step 3: We consider the new divisor 493 and the new remainder 8, and apply the division lemma to get

493 = 8 x 61 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 501 and 994 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(493,8) = HCF(501,493) = HCF(994,501) .


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

Step 1: Since 660 > 1, we apply the division lemma to 660 and 1, to get

660 = 1 x 660 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 660 is 1

Notice that 1 = HCF(660,1) .


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

Step 1: Since 77 > 1, we apply the division lemma to 77 and 1, to get

77 = 1 x 77 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 77 is 1

Notice that 1 = HCF(77,1) .
