HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 412, 655 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 412, 655 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 412, 655 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 412, 655 is 1.

HCF(412, 655) = 1

Highest common factor (HCF) of 412, 655 is 1.

Highest Common Factor of 412,655 using Euclid's algorithm

Highest Common Factor of 412,655 is 1

Step 1: Since 655 > 412, we apply the division lemma to 655 and 412, to get

655 = 412 x 1 + 243

Step 2: Since the reminder 412 ≠ 0, we apply division lemma to 243 and 412, to get

412 = 243 x 1 + 169

Step 3: We consider the new divisor 243 and the new remainder 169, and apply the division lemma to get

243 = 169 x 1 + 74

We consider the new divisor 169 and the new remainder 74,and apply the division lemma to get

169 = 74 x 2 + 21

We consider the new divisor 74 and the new remainder 21,and apply the division lemma to get

74 = 21 x 3 + 11

We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get

21 = 11 x 1 + 10

We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get

11 = 10 x 1 + 1

We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get

10 = 1 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 412 and 655 is 1

Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(74,21) = HCF(169,74) = HCF(243,169) = HCF(412,243) = HCF(655,412) .
