HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 558, 218, 268 i.e. 2 the largest integer that leaves a remainder zero for all numbers.

HCF of 558, 218, 268 is 2 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 558, 218, 268 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 558, 218, 268 is 2.

HCF(558, 218, 268) = 2

Highest common factor (HCF) of 558, 218, 268 is 2.

Highest Common Factor of 558,218,268 using Euclid's algorithm

Highest Common Factor of 558,218,268 is 2

Step 1: Since 558 > 218, we apply the division lemma to 558 and 218, to get

558 = 218 x 2 + 122

Step 2: Since the reminder 218 ≠ 0, we apply division lemma to 122 and 218, to get

218 = 122 x 1 + 96

Step 3: We consider the new divisor 122 and the new remainder 96, and apply the division lemma to get

122 = 96 x 1 + 26

We consider the new divisor 96 and the new remainder 26,and apply the division lemma to get

96 = 26 x 3 + 18

We consider the new divisor 26 and the new remainder 18,and apply the division lemma to get

26 = 18 x 1 + 8

We consider the new divisor 18 and the new remainder 8,and apply the division lemma to get

18 = 8 x 2 + 2

We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get

8 = 2 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 558 and 218 is 2

Notice that 2 = HCF(8,2) = HCF(18,8) = HCF(26,18) = HCF(96,26) = HCF(122,96) = HCF(218,122) = HCF(558,218) .

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

Step 1: Since 268 > 2, we apply the division lemma to 268 and 2, to get

268 = 2 x 134 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 268 is 2

Notice that 2 = HCF(268,2) .
