HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 735, 780, 253 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 735, 780, 253 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 735, 780, 253 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 735, 780, 253 is 1.

HCF(735, 780, 253) = 1

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

HCF of:

Highest common factor (HCF) of 735, 780, 253 is 1.

Highest Common Factor of 735,780,253 using Euclid's algorithm

Highest Common Factor of 735,780,253 is 1

Step 1: Since 780 > 735, we apply the division lemma to 780 and 735, to get

780 = 735 x 1 + 45

Step 2: Since the reminder 735 ≠ 0, we apply division lemma to 45 and 735, to get

735 = 45 x 16 + 15

Step 3: We consider the new divisor 45 and the new remainder 15, and apply the division lemma to get

45 = 15 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 735 and 780 is 15

Notice that 15 = HCF(45,15) = HCF(735,45) = HCF(780,735) .

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

Step 1: Since 253 > 15, we apply the division lemma to 253 and 15, to get

253 = 15 x 16 + 13

Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 13 and 15, to get

15 = 13 x 1 + 2

Step 3: We consider the new divisor 13 and the new remainder 2, and apply the division lemma to get

13 = 2 x 6 + 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 15 and 253 is 1

Notice that 1 = HCF(2,1) = HCF(13,2) = HCF(15,13) = HCF(253,15) .
