HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 581, 356, 64 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 581, 356, 64 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, 356, 64 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, 356, 64 is 1.

HCF(581, 356, 64) = 1

Highest common factor (HCF) of 581, 356, 64 is 1.

Highest Common Factor of 581,356,64 using Euclid's algorithm

Highest Common Factor of 581,356,64 is 1

Step 1: Since 581 > 356, we apply the division lemma to 581 and 356, to get

581 = 356 x 1 + 225

Step 2: Since the reminder 356 ≠ 0, we apply division lemma to 225 and 356, to get

356 = 225 x 1 + 131

Step 3: We consider the new divisor 225 and the new remainder 131, and apply the division lemma to get

225 = 131 x 1 + 94

We consider the new divisor 131 and the new remainder 94,and apply the division lemma to get

131 = 94 x 1 + 37

We consider the new divisor 94 and the new remainder 37,and apply the division lemma to get

94 = 37 x 2 + 20

We consider the new divisor 37 and the new remainder 20,and apply the division lemma to get

37 = 20 x 1 + 17

We consider the new divisor 20 and the new remainder 17,and apply the division lemma to get

20 = 17 x 1 + 3

We consider the new divisor 17 and the new remainder 3,and apply the division lemma to get

17 = 3 x 5 + 2

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

3 = 2 x 1 + 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 581 and 356 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(20,17) = HCF(37,20) = HCF(94,37) = HCF(131,94) = HCF(225,131) = HCF(356,225) = HCF(581,356) .

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

Step 1: Since 64 > 1, we apply the division lemma to 64 and 1, to get

64 = 1 x 64 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 64 is 1

Notice that 1 = HCF(64,1) .
