HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 625, 401, 80, 297 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 625, 401, 80, 297 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 625, 401, 80, 297 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 625, 401, 80, 297 is 1.

HCF(625, 401, 80, 297) = 1

Highest common factor (HCF) of 625, 401, 80, 297 is 1.

Highest Common Factor of 625,401,80,297 using Euclid's algorithm

Highest Common Factor of 625,401,80,297 is 1

Step 1: Since 625 > 401, we apply the division lemma to 625 and 401, to get

625 = 401 x 1 + 224

Step 2: Since the reminder 401 ≠ 0, we apply division lemma to 224 and 401, to get

401 = 224 x 1 + 177

Step 3: We consider the new divisor 224 and the new remainder 177, and apply the division lemma to get

224 = 177 x 1 + 47

We consider the new divisor 177 and the new remainder 47,and apply the division lemma to get

177 = 47 x 3 + 36

We consider the new divisor 47 and the new remainder 36,and apply the division lemma to get

47 = 36 x 1 + 11

We consider the new divisor 36 and the new remainder 11,and apply the division lemma to get

36 = 11 x 3 + 3

We consider the new divisor 11 and the new remainder 3,and apply the division lemma to get

11 = 3 x 3 + 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 625 and 401 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(36,11) = HCF(47,36) = HCF(177,47) = HCF(224,177) = HCF(401,224) = HCF(625,401) .


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

Step 1: Since 80 > 1, we apply the division lemma to 80 and 1, to get

80 = 1 x 80 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 80 is 1

Notice that 1 = HCF(80,1) .


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

Step 1: Since 297 > 1, we apply the division lemma to 297 and 1, to get

297 = 1 x 297 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 297 is 1

Notice that 1 = HCF(297,1) .
