HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 330, 69, 986, 681 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 330, 69, 986, 681 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 330, 69, 986, 681 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 330, 69, 986, 681 is 1.

HCF(330, 69, 986, 681) = 1

Highest common factor (HCF) of 330, 69, 986, 681 is 1.

Highest Common Factor of 330,69,986,681 using Euclid's algorithm

Highest Common Factor of 330,69,986,681 is 1

Step 1: Since 330 > 69, we apply the division lemma to 330 and 69, to get

330 = 69 x 4 + 54

Step 2: Since the reminder 69 ≠ 0, we apply division lemma to 54 and 69, to get

69 = 54 x 1 + 15

Step 3: We consider the new divisor 54 and the new remainder 15, and apply the division lemma to get

54 = 15 x 3 + 9

We consider the new divisor 15 and the new remainder 9,and apply the division lemma to get

15 = 9 x 1 + 6

We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get

9 = 6 x 1 + 3

We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get

6 = 3 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 330 and 69 is 3

Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(15,9) = HCF(54,15) = HCF(69,54) = HCF(330,69) .


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

Step 1: Since 986 > 3, we apply the division lemma to 986 and 3, to get

986 = 3 x 328 + 2

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

3 = 2 x 1 + 1

Step 3: 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 3 and 986 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(986,3) .


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

Step 1: Since 681 > 1, we apply the division lemma to 681 and 1, to get

681 = 1 x 681 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 681 is 1

Notice that 1 = HCF(681,1) .
