HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 372, 720, 629 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 372, 720, 629 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, 720, 629 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, 720, 629 is 1.

HCF(372, 720, 629) = 1

Highest common factor (HCF) of 372, 720, 629 is 1.

Highest Common Factor of 372,720,629 using Euclid's algorithm

Highest Common Factor of 372,720,629 is 1

Step 1: Since 720 > 372, we apply the division lemma to 720 and 372, to get

720 = 372 x 1 + 348

Step 2: Since the reminder 372 ≠ 0, we apply division lemma to 348 and 372, to get

372 = 348 x 1 + 24

Step 3: We consider the new divisor 348 and the new remainder 24, and apply the division lemma to get

348 = 24 x 14 + 12

We consider the new divisor 24 and the new remainder 12, and apply the division lemma to get

24 = 12 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 12, the HCF of 372 and 720 is 12

Notice that 12 = HCF(24,12) = HCF(348,24) = HCF(372,348) = HCF(720,372) .

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

Step 1: Since 629 > 12, we apply the division lemma to 629 and 12, to get

629 = 12 x 52 + 5

Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 5 and 12, to get

12 = 5 x 2 + 2

Step 3: We consider the new divisor 5 and the new remainder 2, and apply the division lemma to get

5 = 2 x 2 + 1

We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get

2 = 1 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 12 and 629 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(629,12) .
