HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 270, 405, 778 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 270, 405, 778 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 270, 405, 778 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 270, 405, 778 is 1.

HCF(270, 405, 778) = 1

HCF of 270, 405, 778 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 270, 405, 778 is 1.

Highest Common Factor of 270,405,778 using Euclid's algorithm

Highest Common Factor of 270,405,778 is 1

Step 1: Since 405 > 270, we apply the division lemma to 405 and 270, to get

405 = 270 x 1 + 135

Step 2: Since the reminder 270 ≠ 0, we apply division lemma to 135 and 270, to get

270 = 135 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 135, the HCF of 270 and 405 is 135

Notice that 135 = HCF(270,135) = HCF(405,270) .


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

Step 1: Since 778 > 135, we apply the division lemma to 778 and 135, to get

778 = 135 x 5 + 103

Step 2: Since the reminder 135 ≠ 0, we apply division lemma to 103 and 135, to get

135 = 103 x 1 + 32

Step 3: We consider the new divisor 103 and the new remainder 32, and apply the division lemma to get

103 = 32 x 3 + 7

We consider the new divisor 32 and the new remainder 7,and apply the division lemma to get

32 = 7 x 4 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 135 and 778 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(32,7) = HCF(103,32) = HCF(135,103) = HCF(778,135) .
