HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 452, 873, 661 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 452, 873, 661 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 452, 873, 661 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 452, 873, 661 is 1.

HCF(452, 873, 661) = 1

HCF of 452, 873, 661 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 452, 873, 661 is 1.

Highest Common Factor of 452,873,661 using Euclid's algorithm

Highest Common Factor of 452,873,661 is 1

Step 1: Since 873 > 452, we apply the division lemma to 873 and 452, to get

873 = 452 x 1 + 421

Step 2: Since the reminder 452 ≠ 0, we apply division lemma to 421 and 452, to get

452 = 421 x 1 + 31

Step 3: We consider the new divisor 421 and the new remainder 31, and apply the division lemma to get

421 = 31 x 13 + 18

We consider the new divisor 31 and the new remainder 18,and apply the division lemma to get

31 = 18 x 1 + 13

We consider the new divisor 18 and the new remainder 13,and apply the division lemma to get

18 = 13 x 1 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 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 452 and 873 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(18,13) = HCF(31,18) = HCF(421,31) = HCF(452,421) = HCF(873,452) .

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

Step 1: Since 661 > 1, we apply the division lemma to 661 and 1, to get

661 = 1 x 661 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 661 is 1

Notice that 1 = HCF(661,1) .
