HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 50, 97, 23, 490 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 50, 97, 23, 490 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 50, 97, 23, 490 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 50, 97, 23, 490 is 1.

HCF(50, 97, 23, 490) = 1

HCF of 50, 97, 23, 490 using Euclid's algorithm

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

HCF of:

Highest common factor (HCF) of 50, 97, 23, 490 is 1.

Highest Common Factor of 50,97,23,490 using Euclid's algorithm

Highest Common Factor of 50,97,23,490 is 1

Step 1: Since 97 > 50, we apply the division lemma to 97 and 50, to get

97 = 50 x 1 + 47

Step 2: Since the reminder 50 ≠ 0, we apply division lemma to 47 and 50, to get

50 = 47 x 1 + 3

Step 3: We consider the new divisor 47 and the new remainder 3, and apply the division lemma to get

47 = 3 x 15 + 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 50 and 97 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(47,3) = HCF(50,47) = HCF(97,50) .


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

Step 1: Since 23 > 1, we apply the division lemma to 23 and 1, to get

23 = 1 x 23 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 23 is 1

Notice that 1 = HCF(23,1) .


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

Step 1: Since 490 > 1, we apply the division lemma to 490 and 1, to get

490 = 1 x 490 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 490 is 1

Notice that 1 = HCF(490,1) .
