HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 369, 80 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 369, 80 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 369, 80 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 369, 80 is 1.

HCF(369, 80) = 1

Highest Common Factor of 369,80 using Euclid's algorithm

Highest Common Factor of 369,80 is 1

Step 1: Since 369 > 80, we apply the division lemma to 369 and 80, to get

369 = 80 x 4 + 49

Step 2: Since the reminder 80 ≠ 0, we apply division lemma to 49 and 80, to get

80 = 49 x 1 + 31

Step 3: We consider the new divisor 49 and the new remainder 31, and apply the division lemma to get

49 = 31 x 1 + 18

We consider the new divisor 31 and the new remainder 18,and apply the division lemma to get

31 = 18 x 1 + 13

We consider the new divisor 18 and the new remainder 13,and apply the division lemma to get

18 = 13 x 1 + 5

We consider the new divisor 13 and the new remainder 5,and apply the division lemma to get

13 = 5 x 2 + 3

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

5 = 3 x 1 + 2

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

3 = 2 x 1 + 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 369 and 80 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(13,5) = HCF(18,13) = HCF(31,18) = HCF(49,31) = HCF(80,49) = HCF(369,80) .
