HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 181, 390, 994 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 497, 181, 390, 994 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 497, 181, 390, 994 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 497, 181, 390, 994 is 1.

HCF(497, 181, 390, 994) = 1

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

HCF of:

Highest common factor (HCF) of 497, 181, 390, 994 is 1.

Highest Common Factor of 497,181,390,994 using Euclid's algorithm

Highest Common Factor of 497,181,390,994 is 1

Step 1: Since 497 > 181, we apply the division lemma to 497 and 181, to get

497 = 181 x 2 + 135

Step 2: Since the reminder 181 ≠ 0, we apply division lemma to 135 and 181, to get

181 = 135 x 1 + 46

Step 3: We consider the new divisor 135 and the new remainder 46, and apply the division lemma to get

135 = 46 x 2 + 43

We consider the new divisor 46 and the new remainder 43,and apply the division lemma to get

46 = 43 x 1 + 3

We consider the new divisor 43 and the new remainder 3,and apply the division lemma to get

43 = 3 x 14 + 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 497 and 181 is 1

Notice that 1 = HCF(3,1) = HCF(43,3) = HCF(46,43) = HCF(135,46) = HCF(181,135) = HCF(497,181) .


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

Step 1: Since 390 > 1, we apply the division lemma to 390 and 1, to get

390 = 1 x 390 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 390 is 1

Notice that 1 = HCF(390,1) .


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

Step 1: Since 994 > 1, we apply the division lemma to 994 and 1, to get

994 = 1 x 994 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 994 is 1

Notice that 1 = HCF(994,1) .
