HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 591, 742, 430, 218 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 591, 742, 430, 218 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 591, 742, 430, 218 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 591, 742, 430, 218 is 1.

HCF(591, 742, 430, 218) = 1

Highest Common Factor of 591,742,430,218 using Euclid's algorithm

Highest Common Factor of 591,742,430,218 is 1

Step 1: Since 742 > 591, we apply the division lemma to 742 and 591, to get

742 = 591 x 1 + 151

Step 2: Since the reminder 591 ≠ 0, we apply division lemma to 151 and 591, to get

591 = 151 x 3 + 138

Step 3: We consider the new divisor 151 and the new remainder 138, and apply the division lemma to get

151 = 138 x 1 + 13

We consider the new divisor 138 and the new remainder 13,and apply the division lemma to get

138 = 13 x 10 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 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 591 and 742 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(138,13) = HCF(151,138) = HCF(591,151) = HCF(742,591) .

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

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

430 = 1 x 430 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 430 is 1

Notice that 1 = HCF(430,1) .

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

Step 1: Since 218 > 1, we apply the division lemma to 218 and 1, to get

218 = 1 x 218 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 218 is 1

Notice that 1 = HCF(218,1) .
