HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 418, 399 i.e. 19 the largest integer that leaves a remainder zero for all numbers.

HCF of 418, 399 is 19 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 418, 399 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 418, 399 is 19.

HCF(418, 399) = 19

HCF of 418, 399 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 418, 399 is 19.

Highest Common Factor of 418,399 using Euclid's algorithm

Highest Common Factor of 418,399 is 19

Step 1: Since 418 > 399, we apply the division lemma to 418 and 399, to get

418 = 399 x 1 + 19

Step 2: Since the reminder 399 ≠ 0, we apply division lemma to 19 and 399, to get

399 = 19 x 21 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 418 and 399 is 19

Notice that 19 = HCF(399,19) = HCF(418,399) .
