HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 720, 220, 718 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 720, 220, 718 is 2 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 720, 220, 718 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 720, 220, 718 is 2.

HCF(720, 220, 718) = 2

HCF of 720, 220, 718 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 720, 220, 718 is 2.

Highest Common Factor of 720,220,718 using Euclid's algorithm

Highest Common Factor of 720,220,718 is 2

Step 1: Since 720 > 220, we apply the division lemma to 720 and 220, to get

720 = 220 x 3 + 60

Step 2: Since the reminder 220 ≠ 0, we apply division lemma to 60 and 220, to get

220 = 60 x 3 + 40

Step 3: We consider the new divisor 60 and the new remainder 40, and apply the division lemma to get

60 = 40 x 1 + 20

We consider the new divisor 40 and the new remainder 20, and apply the division lemma to get

40 = 20 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 20, the HCF of 720 and 220 is 20

Notice that 20 = HCF(40,20) = HCF(60,40) = HCF(220,60) = HCF(720,220) .

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

Step 1: Since 718 > 20, we apply the division lemma to 718 and 20, to get

718 = 20 x 35 + 18

Step 2: Since the reminder 20 ≠ 0, we apply division lemma to 18 and 20, to get

20 = 18 x 1 + 2

Step 3: We consider the new divisor 18 and the new remainder 2, and apply the division lemma to get

18 = 2 x 9 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 20 and 718 is 2

Notice that 2 = HCF(18,2) = HCF(20,18) = HCF(718,20) .
