HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 497, 407, 61, 273 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 497, 407, 61, 273 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, 407, 61, 273 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, 407, 61, 273 is 1.

HCF(497, 407, 61, 273) = 1

Highest common factor (HCF) of 497, 407, 61, 273 is 1.

Highest Common Factor of 497,407,61,273 using Euclid's algorithm

Highest Common Factor of 497,407,61,273 is 1

Step 1: Since 497 > 407, we apply the division lemma to 497 and 407, to get

497 = 407 x 1 + 90

Step 2: Since the reminder 407 ≠ 0, we apply division lemma to 90 and 407, to get

407 = 90 x 4 + 47

Step 3: We consider the new divisor 90 and the new remainder 47, and apply the division lemma to get

90 = 47 x 1 + 43

We consider the new divisor 47 and the new remainder 43,and apply the division lemma to get

47 = 43 x 1 + 4

We consider the new divisor 43 and the new remainder 4,and apply the division lemma to get

43 = 4 x 10 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 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 407 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(43,4) = HCF(47,43) = HCF(90,47) = HCF(407,90) = HCF(497,407) .

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

Step 1: Since 61 > 1, we apply the division lemma to 61 and 1, to get

61 = 1 x 61 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 61 is 1

Notice that 1 = HCF(61,1) .

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

Step 1: Since 273 > 1, we apply the division lemma to 273 and 1, to get

273 = 1 x 273 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 273 is 1

Notice that 1 = HCF(273,1) .
