HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 581, 430, 675 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 581, 430, 675 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 581, 430, 675 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 581, 430, 675 is 1.

HCF(581, 430, 675) = 1

HCF of 581, 430, 675 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 581, 430, 675 is 1.

Highest Common Factor of 581,430,675 using Euclid's algorithm

Highest Common Factor of 581,430,675 is 1

Step 1: Since 581 > 430, we apply the division lemma to 581 and 430, to get

581 = 430 x 1 + 151

Step 2: Since the reminder 430 ≠ 0, we apply division lemma to 151 and 430, to get

430 = 151 x 2 + 128

Step 3: We consider the new divisor 151 and the new remainder 128, and apply the division lemma to get

151 = 128 x 1 + 23

We consider the new divisor 128 and the new remainder 23,and apply the division lemma to get

128 = 23 x 5 + 13

We consider the new divisor 23 and the new remainder 13,and apply the division lemma to get

23 = 13 x 1 + 10

We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get

13 = 10 x 1 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 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 581 and 430 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(23,13) = HCF(128,23) = HCF(151,128) = HCF(430,151) = HCF(581,430) .

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

Step 1: Since 675 > 1, we apply the division lemma to 675 and 1, to get

675 = 1 x 675 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 675 is 1

Notice that 1 = HCF(675,1) .
