HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 660, 779, 24, 668 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 660, 779, 24, 668 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 660, 779, 24, 668 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 660, 779, 24, 668 is 1.

HCF(660, 779, 24, 668) = 1

Highest common factor (HCF) of 660, 779, 24, 668 is 1.

Highest Common Factor of 660,779,24,668 using Euclid's algorithm

Highest Common Factor of 660,779,24,668 is 1

Step 1: Since 779 > 660, we apply the division lemma to 779 and 660, to get

779 = 660 x 1 + 119

Step 2: Since the reminder 660 ≠ 0, we apply division lemma to 119 and 660, to get

660 = 119 x 5 + 65

Step 3: We consider the new divisor 119 and the new remainder 65, and apply the division lemma to get

119 = 65 x 1 + 54

We consider the new divisor 65 and the new remainder 54,and apply the division lemma to get

65 = 54 x 1 + 11

We consider the new divisor 54 and the new remainder 11,and apply the division lemma to get

54 = 11 x 4 + 10

We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get

11 = 10 x 1 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 660 and 779 is 1

Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(54,11) = HCF(65,54) = HCF(119,65) = HCF(660,119) = HCF(779,660) .


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

Step 1: Since 24 > 1, we apply the division lemma to 24 and 1, to get

24 = 1 x 24 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 24 is 1

Notice that 1 = HCF(24,1) .


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

Step 1: Since 668 > 1, we apply the division lemma to 668 and 1, to get

668 = 1 x 668 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 668 is 1

Notice that 1 = HCF(668,1) .
