HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 903, 520, 316 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 903, 520, 316 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 903, 520, 316 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 903, 520, 316 is 1.

HCF(903, 520, 316) = 1

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

HCF of:

Highest common factor (HCF) of 903, 520, 316 is 1.

Highest Common Factor of 903,520,316 using Euclid's algorithm

Highest Common Factor of 903,520,316 is 1

Step 1: Since 903 > 520, we apply the division lemma to 903 and 520, to get

903 = 520 x 1 + 383

Step 2: Since the reminder 520 ≠ 0, we apply division lemma to 383 and 520, to get

520 = 383 x 1 + 137

Step 3: We consider the new divisor 383 and the new remainder 137, and apply the division lemma to get

383 = 137 x 2 + 109

We consider the new divisor 137 and the new remainder 109,and apply the division lemma to get

137 = 109 x 1 + 28

We consider the new divisor 109 and the new remainder 28,and apply the division lemma to get

109 = 28 x 3 + 25

We consider the new divisor 28 and the new remainder 25,and apply the division lemma to get

28 = 25 x 1 + 3

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

25 = 3 x 8 + 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 903 and 520 is 1

Notice that 1 = HCF(3,1) = HCF(25,3) = HCF(28,25) = HCF(109,28) = HCF(137,109) = HCF(383,137) = HCF(520,383) = HCF(903,520) .

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

Step 1: Since 316 > 1, we apply the division lemma to 316 and 1, to get

316 = 1 x 316 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 316 is 1

Notice that 1 = HCF(316,1) .
