HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 372, 408, 99 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 372, 408, 99 is 3 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 372, 408, 99 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 372, 408, 99 is 3.

HCF(372, 408, 99) = 3

HCF of 372, 408, 99 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 372, 408, 99 is 3.

Highest Common Factor of 372,408,99 using Euclid's algorithm

Highest Common Factor of 372,408,99 is 3

Step 1: Since 408 > 372, we apply the division lemma to 408 and 372, to get

408 = 372 x 1 + 36

Step 2: Since the reminder 372 ≠ 0, we apply division lemma to 36 and 372, to get

372 = 36 x 10 + 12

Step 3: We consider the new divisor 36 and the new remainder 12, and apply the division lemma to get

36 = 12 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 372 and 408 is 12

Notice that 12 = HCF(36,12) = HCF(372,36) = HCF(408,372) .


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

Step 1: Since 99 > 12, we apply the division lemma to 99 and 12, to get

99 = 12 x 8 + 3

Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 3 and 12, to get

12 = 3 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 12 and 99 is 3

Notice that 3 = HCF(12,3) = HCF(99,12) .
