HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 720, 211, 130 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 720, 211, 130 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 720, 211, 130 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, 211, 130 is 1.

HCF(720, 211, 130) = 1

Highest common factor (HCF) of 720, 211, 130 is 1.

Highest Common Factor of 720,211,130 using Euclid's algorithm

Highest Common Factor of 720,211,130 is 1

Step 1: Since 720 > 211, we apply the division lemma to 720 and 211, to get

720 = 211 x 3 + 87

Step 2: Since the reminder 211 ≠ 0, we apply division lemma to 87 and 211, to get

211 = 87 x 2 + 37

Step 3: We consider the new divisor 87 and the new remainder 37, and apply the division lemma to get

87 = 37 x 2 + 13

We consider the new divisor 37 and the new remainder 13,and apply the division lemma to get

37 = 13 x 2 + 11

We consider the new divisor 13 and the new remainder 11,and apply the division lemma to get

13 = 11 x 1 + 2

We consider the new divisor 11 and the new remainder 2,and apply the division lemma to get

11 = 2 x 5 + 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 720 and 211 is 1

Notice that 1 = HCF(2,1) = HCF(11,2) = HCF(13,11) = HCF(37,13) = HCF(87,37) = HCF(211,87) = HCF(720,211) .

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

Step 1: Since 130 > 1, we apply the division lemma to 130 and 1, to get

130 = 1 x 130 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 130 is 1

Notice that 1 = HCF(130,1) .
