HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 406, 555 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 406, 555 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 406, 555 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 406, 555 is 1.

HCF(406, 555) = 1

Highest common factor (HCF) of 406, 555 is 1.

Highest Common Factor of 406,555 using Euclid's algorithm

Highest Common Factor of 406,555 is 1

Step 1: Since 555 > 406, we apply the division lemma to 555 and 406, to get

555 = 406 x 1 + 149

Step 2: Since the reminder 406 ≠ 0, we apply division lemma to 149 and 406, to get

406 = 149 x 2 + 108

Step 3: We consider the new divisor 149 and the new remainder 108, and apply the division lemma to get

149 = 108 x 1 + 41

We consider the new divisor 108 and the new remainder 41,and apply the division lemma to get

108 = 41 x 2 + 26

We consider the new divisor 41 and the new remainder 26,and apply the division lemma to get

41 = 26 x 1 + 15

We consider the new divisor 26 and the new remainder 15,and apply the division lemma to get

26 = 15 x 1 + 11

We consider the new divisor 15 and the new remainder 11,and apply the division lemma to get

15 = 11 x 1 + 4

We consider the new divisor 11 and the new remainder 4,and apply the division lemma to get

11 = 4 x 2 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 406 and 555 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(11,4) = HCF(15,11) = HCF(26,15) = HCF(41,26) = HCF(108,41) = HCF(149,108) = HCF(406,149) = HCF(555,406) .
