HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 68, 501, 351 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 68, 501, 351 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 68, 501, 351 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 68, 501, 351 is 1.

HCF(68, 501, 351) = 1

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 68, 501, 351 is 1.

Highest Common Factor of 68,501,351 using Euclid's algorithm

Highest Common Factor of 68,501,351 is 1

Step 1: Since 501 > 68, we apply the division lemma to 501 and 68, to get

501 = 68 x 7 + 25

Step 2: Since the reminder 68 ≠ 0, we apply division lemma to 25 and 68, to get

68 = 25 x 2 + 18

Step 3: We consider the new divisor 25 and the new remainder 18, and apply the division lemma to get

25 = 18 x 1 + 7

We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get

18 = 7 x 2 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 68 and 501 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(25,18) = HCF(68,25) = HCF(501,68) .

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

Step 1: Since 351 > 1, we apply the division lemma to 351 and 1, to get

351 = 1 x 351 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 351 is 1

Notice that 1 = HCF(351,1) .
