HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 330, 379, 653 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 330, 379, 653 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, 379, 653 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, 379, 653 is 1.

HCF(330, 379, 653) = 1

Highest common factor (HCF) of 330, 379, 653 is 1.

Highest Common Factor of 330,379,653 using Euclid's algorithm

Highest Common Factor of 330,379,653 is 1

Step 1: Since 379 > 330, we apply the division lemma to 379 and 330, to get

379 = 330 x 1 + 49

Step 2: Since the reminder 330 ≠ 0, we apply division lemma to 49 and 330, to get

330 = 49 x 6 + 36

Step 3: We consider the new divisor 49 and the new remainder 36, and apply the division lemma to get

49 = 36 x 1 + 13

We consider the new divisor 36 and the new remainder 13,and apply the division lemma to get

36 = 13 x 2 + 10

We consider the new divisor 13 and the new remainder 10,and apply the division lemma to get

13 = 10 x 1 + 3

We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get

10 = 3 x 3 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 330 and 379 is 1

Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(13,10) = HCF(36,13) = HCF(49,36) = HCF(330,49) = HCF(379,330) .

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

Step 1: Since 653 > 1, we apply the division lemma to 653 and 1, to get

653 = 1 x 653 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 653 is 1

Notice that 1 = HCF(653,1) .
