HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 372, 291, 808 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 372, 291, 808 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 372, 291, 808 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, 291, 808 is 1.

HCF(372, 291, 808) = 1

Highest common factor (HCF) of 372, 291, 808 is 1.

Highest Common Factor of 372,291,808 using Euclid's algorithm

Highest Common Factor of 372,291,808 is 1

Step 1: Since 372 > 291, we apply the division lemma to 372 and 291, to get

372 = 291 x 1 + 81

Step 2: Since the reminder 291 ≠ 0, we apply division lemma to 81 and 291, to get

291 = 81 x 3 + 48

Step 3: We consider the new divisor 81 and the new remainder 48, and apply the division lemma to get

81 = 48 x 1 + 33

We consider the new divisor 48 and the new remainder 33,and apply the division lemma to get

48 = 33 x 1 + 15

We consider the new divisor 33 and the new remainder 15,and apply the division lemma to get

33 = 15 x 2 + 3

We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get

15 = 3 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 372 and 291 is 3

Notice that 3 = HCF(15,3) = HCF(33,15) = HCF(48,33) = HCF(81,48) = HCF(291,81) = HCF(372,291) .

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

Step 1: Since 808 > 3, we apply the division lemma to 808 and 3, to get

808 = 3 x 269 + 1

Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 808 is 1

Notice that 1 = HCF(3,1) = HCF(808,3) .
