HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 702, 781, 388 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 702, 781, 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 702, 781, 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 702, 781, 388 is 1.

HCF(702, 781, 388) = 1

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

HCF of:

Highest common factor (HCF) of 702, 781, 388 is 1.

Highest Common Factor of 702,781,388 using Euclid's algorithm

Highest Common Factor of 702,781,388 is 1

Step 1: Since 781 > 702, we apply the division lemma to 781 and 702, to get

781 = 702 x 1 + 79

Step 2: Since the reminder 702 ≠ 0, we apply division lemma to 79 and 702, to get

702 = 79 x 8 + 70

Step 3: We consider the new divisor 79 and the new remainder 70, and apply the division lemma to get

79 = 70 x 1 + 9

We consider the new divisor 70 and the new remainder 9,and apply the division lemma to get

70 = 9 x 7 + 7

We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get

9 = 7 x 1 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 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 702 and 781 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(70,9) = HCF(79,70) = HCF(702,79) = HCF(781,702) .

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) .
