HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 485, 349, 732 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 485, 349, 732 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 485, 349, 732 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 485, 349, 732 is 1.

HCF(485, 349, 732) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 485, 349, 732 is 1.

Highest Common Factor of 485,349,732 using Euclid's algorithm

Highest Common Factor of 485,349,732 is 1

Step 1: Since 485 > 349, we apply the division lemma to 485 and 349, to get

485 = 349 x 1 + 136

Step 2: Since the reminder 349 ≠ 0, we apply division lemma to 136 and 349, to get

349 = 136 x 2 + 77

Step 3: We consider the new divisor 136 and the new remainder 77, and apply the division lemma to get

136 = 77 x 1 + 59

We consider the new divisor 77 and the new remainder 59,and apply the division lemma to get

77 = 59 x 1 + 18

We consider the new divisor 59 and the new remainder 18,and apply the division lemma to get

59 = 18 x 3 + 5

We consider the new divisor 18 and the new remainder 5,and apply the division lemma to get

18 = 5 x 3 + 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 485 and 349 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(18,5) = HCF(59,18) = HCF(77,59) = HCF(136,77) = HCF(349,136) = HCF(485,349) .

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

Step 1: Since 732 > 1, we apply the division lemma to 732 and 1, to get

732 = 1 x 732 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 732 is 1

Notice that 1 = HCF(732,1) .
