HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 986, 577, 459 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 986, 577, 459 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, 577, 459 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, 577, 459 is 1.

HCF(986, 577, 459) = 1

Highest common factor (HCF) of 986, 577, 459 is 1.

Highest Common Factor of 986,577,459 using Euclid's algorithm

Highest Common Factor of 986,577,459 is 1

Step 1: Since 986 > 577, we apply the division lemma to 986 and 577, to get

986 = 577 x 1 + 409

Step 2: Since the reminder 577 ≠ 0, we apply division lemma to 409 and 577, to get

577 = 409 x 1 + 168

Step 3: We consider the new divisor 409 and the new remainder 168, and apply the division lemma to get

409 = 168 x 2 + 73

We consider the new divisor 168 and the new remainder 73,and apply the division lemma to get

168 = 73 x 2 + 22

We consider the new divisor 73 and the new remainder 22,and apply the division lemma to get

73 = 22 x 3 + 7

We consider the new divisor 22 and the new remainder 7,and apply the division lemma to get

22 = 7 x 3 + 1

We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get

7 = 1 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 986 and 577 is 1

Notice that 1 = HCF(7,1) = HCF(22,7) = HCF(73,22) = HCF(168,73) = HCF(409,168) = HCF(577,409) = HCF(986,577) .

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

Step 1: Since 459 > 1, we apply the division lemma to 459 and 1, to get

459 = 1 x 459 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 459 is 1

Notice that 1 = HCF(459,1) .
