HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 918, 645, 759 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 918, 645, 759 is 3 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 918, 645, 759 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 918, 645, 759 is 3.

HCF(918, 645, 759) = 3

HCF of 918, 645, 759 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 918, 645, 759 is 3.

Highest Common Factor of 918,645,759 using Euclid's algorithm

Highest Common Factor of 918,645,759 is 3

Step 1: Since 918 > 645, we apply the division lemma to 918 and 645, to get

918 = 645 x 1 + 273

Step 2: Since the reminder 645 ≠ 0, we apply division lemma to 273 and 645, to get

645 = 273 x 2 + 99

Step 3: We consider the new divisor 273 and the new remainder 99, and apply the division lemma to get

273 = 99 x 2 + 75

We consider the new divisor 99 and the new remainder 75,and apply the division lemma to get

99 = 75 x 1 + 24

We consider the new divisor 75 and the new remainder 24,and apply the division lemma to get

75 = 24 x 3 + 3

We consider the new divisor 24 and the new remainder 3,and apply the division lemma to get

24 = 3 x 8 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 918 and 645 is 3

Notice that 3 = HCF(24,3) = HCF(75,24) = HCF(99,75) = HCF(273,99) = HCF(645,273) = HCF(918,645) .


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

Step 1: Since 759 > 3, we apply the division lemma to 759 and 3, to get

759 = 3 x 253 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 759 is 3

Notice that 3 = HCF(759,3) .
