HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 986, 720, 365 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 986, 720, 365 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 986, 720, 365 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 986, 720, 365 is 1.

HCF(986, 720, 365) = 1

Highest common factor (HCF) of 986, 720, 365 is 1.

Highest Common Factor of 986,720,365 using Euclid's algorithm

Highest Common Factor of 986,720,365 is 1

Step 1: Since 986 > 720, we apply the division lemma to 986 and 720, to get

986 = 720 x 1 + 266

Step 2: Since the reminder 720 ≠ 0, we apply division lemma to 266 and 720, to get

720 = 266 x 2 + 188

Step 3: We consider the new divisor 266 and the new remainder 188, and apply the division lemma to get

266 = 188 x 1 + 78

We consider the new divisor 188 and the new remainder 78,and apply the division lemma to get

188 = 78 x 2 + 32

We consider the new divisor 78 and the new remainder 32,and apply the division lemma to get

78 = 32 x 2 + 14

We consider the new divisor 32 and the new remainder 14,and apply the division lemma to get

32 = 14 x 2 + 4

We consider the new divisor 14 and the new remainder 4,and apply the division lemma to get

14 = 4 x 3 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 986 and 720 is 2

Notice that 2 = HCF(4,2) = HCF(14,4) = HCF(32,14) = HCF(78,32) = HCF(188,78) = HCF(266,188) = HCF(720,266) = HCF(986,720) .

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

Step 1: Since 365 > 2, we apply the division lemma to 365 and 2, to get

365 = 2 x 182 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 365 is 1

Notice that 1 = HCF(2,1) = HCF(365,2) .
