HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 240, 320, 807, 645 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 240, 320, 807, 645 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 240, 320, 807, 645 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 240, 320, 807, 645 is 1.

HCF(240, 320, 807, 645) = 1

HCF of 240, 320, 807, 645 using Euclid's algorithm

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

Highest common factor (HCF) of 240, 320, 807, 645 is 1.

Highest Common Factor of 240,320,807,645 using Euclid's algorithm

Highest Common Factor of 240,320,807,645 is 1

Step 1: Since 320 > 240, we apply the division lemma to 320 and 240, to get

320 = 240 x 1 + 80

Step 2: Since the reminder 240 ≠ 0, we apply division lemma to 80 and 240, to get

240 = 80 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 80, the HCF of 240 and 320 is 80

Notice that 80 = HCF(240,80) = HCF(320,240) .


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

Step 1: Since 807 > 80, we apply the division lemma to 807 and 80, to get

807 = 80 x 10 + 7

Step 2: Since the reminder 80 ≠ 0, we apply division lemma to 7 and 80, to get

80 = 7 x 11 + 3

Step 3: We consider the new divisor 7 and the new remainder 3, and apply the division lemma to get

7 = 3 x 2 + 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 80 and 807 is 1

Notice that 1 = HCF(3,1) = HCF(7,3) = HCF(80,7) = HCF(807,80) .


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

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

645 = 1 x 645 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 645 is 1

Notice that 1 = HCF(645,1) .
