HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 948, 721, 516 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 948, 721, 516 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 948, 721, 516 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 948, 721, 516 is 1.

HCF(948, 721, 516) = 1

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

HCF of:

Highest common factor (HCF) of 948, 721, 516 is 1.

Highest Common Factor of 948,721,516 using Euclid's algorithm

Highest Common Factor of 948,721,516 is 1

Step 1: Since 948 > 721, we apply the division lemma to 948 and 721, to get

948 = 721 x 1 + 227

Step 2: Since the reminder 721 ≠ 0, we apply division lemma to 227 and 721, to get

721 = 227 x 3 + 40

Step 3: We consider the new divisor 227 and the new remainder 40, and apply the division lemma to get

227 = 40 x 5 + 27

We consider the new divisor 40 and the new remainder 27,and apply the division lemma to get

40 = 27 x 1 + 13

We consider the new divisor 27 and the new remainder 13,and apply the division lemma to get

27 = 13 x 2 + 1

We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 948 and 721 is 1

Notice that 1 = HCF(13,1) = HCF(27,13) = HCF(40,27) = HCF(227,40) = HCF(721,227) = HCF(948,721) .

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

Step 1: Since 516 > 1, we apply the division lemma to 516 and 1, to get

516 = 1 x 516 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 516 is 1

Notice that 1 = HCF(516,1) .
