HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 455, 719, 572 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 455, 719, 572 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 455, 719, 572 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 455, 719, 572 is 1.

HCF(455, 719, 572) = 1

Highest common factor (HCF) of 455, 719, 572 is 1.

Highest Common Factor of 455,719,572 using Euclid's algorithm

Highest Common Factor of 455,719,572 is 1

Step 1: Since 719 > 455, we apply the division lemma to 719 and 455, to get

719 = 455 x 1 + 264

Step 2: Since the reminder 455 ≠ 0, we apply division lemma to 264 and 455, to get

455 = 264 x 1 + 191

Step 3: We consider the new divisor 264 and the new remainder 191, and apply the division lemma to get

264 = 191 x 1 + 73

We consider the new divisor 191 and the new remainder 73,and apply the division lemma to get

191 = 73 x 2 + 45

We consider the new divisor 73 and the new remainder 45,and apply the division lemma to get

73 = 45 x 1 + 28

We consider the new divisor 45 and the new remainder 28,and apply the division lemma to get

45 = 28 x 1 + 17

We consider the new divisor 28 and the new remainder 17,and apply the division lemma to get

28 = 17 x 1 + 11

We consider the new divisor 17 and the new remainder 11,and apply the division lemma to get

17 = 11 x 1 + 6

We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get

11 = 6 x 1 + 5

We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get

6 = 5 x 1 + 1

We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get

5 = 1 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 455 and 719 is 1

Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(17,11) = HCF(28,17) = HCF(45,28) = HCF(73,45) = HCF(191,73) = HCF(264,191) = HCF(455,264) = HCF(719,455) .

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

Step 1: Since 572 > 1, we apply the division lemma to 572 and 1, to get

572 = 1 x 572 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 572 is 1

Notice that 1 = HCF(572,1) .
