HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 126, 408 i.e. 6 the largest integer that leaves a remainder zero for all numbers.

HCF of 126, 408 is 6 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 126, 408 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 126, 408 is 6.

HCF(126, 408) = 6

HCF of 126, 408 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 126, 408 is 6.

Highest Common Factor of 126,408 using Euclid's algorithm

Highest Common Factor of 126,408 is 6

Step 1: Since 408 > 126, we apply the division lemma to 408 and 126, to get

408 = 126 x 3 + 30

Step 2: Since the reminder 126 ≠ 0, we apply division lemma to 30 and 126, to get

126 = 30 x 4 + 6

Step 3: We consider the new divisor 30 and the new remainder 6, and apply the division lemma to get

30 = 6 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 126 and 408 is 6

Notice that 6 = HCF(30,6) = HCF(126,30) = HCF(408,126) .
