HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 97, 76, 225, 503 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 97, 76, 225, 503 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 97, 76, 225, 503 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 97, 76, 225, 503 is 1.

HCF(97, 76, 225, 503) = 1

Highest common factor (HCF) of 97, 76, 225, 503 is 1.

Highest Common Factor of 97,76,225,503 using Euclid's algorithm

Highest Common Factor of 97,76,225,503 is 1

Step 1: Since 97 > 76, we apply the division lemma to 97 and 76, to get

97 = 76 x 1 + 21

Step 2: Since the reminder 76 ≠ 0, we apply division lemma to 21 and 76, to get

76 = 21 x 3 + 13

Step 3: We consider the new divisor 21 and the new remainder 13, and apply the division lemma to get

21 = 13 x 1 + 8

We consider the new divisor 13 and the new remainder 8,and apply the division lemma to get

13 = 8 x 1 + 5

We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get

8 = 5 x 1 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 1

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 97 and 76 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(13,8) = HCF(21,13) = HCF(76,21) = HCF(97,76) .

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

Step 1: Since 225 > 1, we apply the division lemma to 225 and 1, to get

225 = 1 x 225 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 225 is 1

Notice that 1 = HCF(225,1) .

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

Step 1: Since 503 > 1, we apply the division lemma to 503 and 1, to get

503 = 1 x 503 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 503 is 1

Notice that 1 = HCF(503,1) .
