HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 123, 461 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 123, 461 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 123, 461 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 123, 461 is 1.

HCF(123, 461) = 1

HCF of 123, 461 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 123, 461 is 1.

Highest Common Factor of 123,461 using Euclid's algorithm

Highest Common Factor of 123,461 is 1

Step 1: Since 461 > 123, we apply the division lemma to 461 and 123, to get

461 = 123 x 3 + 92

Step 2: Since the reminder 123 ≠ 0, we apply division lemma to 92 and 123, to get

123 = 92 x 1 + 31

Step 3: We consider the new divisor 92 and the new remainder 31, and apply the division lemma to get

92 = 31 x 2 + 30

We consider the new divisor 31 and the new remainder 30,and apply the division lemma to get

31 = 30 x 1 + 1

We consider the new divisor 30 and the new remainder 1,and apply the division lemma to get

30 = 1 x 30 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 123 and 461 is 1

Notice that 1 = HCF(30,1) = HCF(31,30) = HCF(92,31) = HCF(123,92) = HCF(461,123) .
