HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 419, 291, 720 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 419, 291, 720 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 419, 291, 720 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 419, 291, 720 is 1.

HCF(419, 291, 720) = 1

Highest common factor (HCF) of 419, 291, 720 is 1.

Highest Common Factor of 419,291,720 using Euclid's algorithm

Highest Common Factor of 419,291,720 is 1

Step 1: Since 419 > 291, we apply the division lemma to 419 and 291, to get

419 = 291 x 1 + 128

Step 2: Since the reminder 291 ≠ 0, we apply division lemma to 128 and 291, to get

291 = 128 x 2 + 35

Step 3: We consider the new divisor 128 and the new remainder 35, and apply the division lemma to get

128 = 35 x 3 + 23

We consider the new divisor 35 and the new remainder 23,and apply the division lemma to get

35 = 23 x 1 + 12

We consider the new divisor 23 and the new remainder 12,and apply the division lemma to get

23 = 12 x 1 + 11

We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get

12 = 11 x 1 + 1

We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 419 and 291 is 1

Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(23,12) = HCF(35,23) = HCF(128,35) = HCF(291,128) = HCF(419,291) .

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

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

720 = 1 x 720 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 720 is 1

Notice that 1 = HCF(720,1) .
