HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 373, 646, 281 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 373, 646, 281 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 373, 646, 281 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 373, 646, 281 is 1.

HCF(373, 646, 281) = 1

Highest common factor (HCF) of 373, 646, 281 is 1.

Highest Common Factor of 373,646,281 using Euclid's algorithm

Highest Common Factor of 373,646,281 is 1

Step 1: Since 646 > 373, we apply the division lemma to 646 and 373, to get

646 = 373 x 1 + 273

Step 2: Since the reminder 373 ≠ 0, we apply division lemma to 273 and 373, to get

373 = 273 x 1 + 100

Step 3: We consider the new divisor 273 and the new remainder 100, and apply the division lemma to get

273 = 100 x 2 + 73

We consider the new divisor 100 and the new remainder 73,and apply the division lemma to get

100 = 73 x 1 + 27

We consider the new divisor 73 and the new remainder 27,and apply the division lemma to get

73 = 27 x 2 + 19

We consider the new divisor 27 and the new remainder 19,and apply the division lemma to get

27 = 19 x 1 + 8

We consider the new divisor 19 and the new remainder 8,and apply the division lemma to get

19 = 8 x 2 + 3

We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get

8 = 3 x 2 + 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 373 and 646 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(19,8) = HCF(27,19) = HCF(73,27) = HCF(100,73) = HCF(273,100) = HCF(373,273) = HCF(646,373) .

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

Step 1: Since 281 > 1, we apply the division lemma to 281 and 1, to get

281 = 1 x 281 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 281 is 1

Notice that 1 = HCF(281,1) .
