HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 720, 782, 419, 388 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 720, 782, 419, 388 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 720, 782, 419, 388 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 720, 782, 419, 388 is 1.

HCF(720, 782, 419, 388) = 1

Highest common factor (HCF) of 720, 782, 419, 388 is 1.

Highest Common Factor of 720,782,419,388 using Euclid's algorithm

Highest Common Factor of 720,782,419,388 is 1

Step 1: Since 782 > 720, we apply the division lemma to 782 and 720, to get

782 = 720 x 1 + 62

Step 2: Since the reminder 720 ≠ 0, we apply division lemma to 62 and 720, to get

720 = 62 x 11 + 38

Step 3: We consider the new divisor 62 and the new remainder 38, and apply the division lemma to get

62 = 38 x 1 + 24

We consider the new divisor 38 and the new remainder 24,and apply the division lemma to get

38 = 24 x 1 + 14

We consider the new divisor 24 and the new remainder 14,and apply the division lemma to get

24 = 14 x 1 + 10

We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get

14 = 10 x 1 + 4

We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get

10 = 4 x 2 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 720 and 782 is 2

Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(24,14) = HCF(38,24) = HCF(62,38) = HCF(720,62) = HCF(782,720) .

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

Step 1: Since 419 > 2, we apply the division lemma to 419 and 2, to get

419 = 2 x 209 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 419 is 1

Notice that 1 = HCF(2,1) = HCF(419,2) .

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

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

388 = 1 x 388 + 0

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

Notice that 1 = HCF(388,1) .
