HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 380, 601, 490 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 380, 601, 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 380, 601, 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 380, 601, 490 is 1.

HCF(380, 601, 490) = 1

Highest Common Factor of 380,601,490 using Euclid's algorithm

Highest Common Factor of 380,601,490 is 1

Step 1: Since 601 > 380, we apply the division lemma to 601 and 380, to get

601 = 380 x 1 + 221

Step 2: Since the reminder 380 ≠ 0, we apply division lemma to 221 and 380, to get

380 = 221 x 1 + 159

Step 3: We consider the new divisor 221 and the new remainder 159, and apply the division lemma to get

221 = 159 x 1 + 62

We consider the new divisor 159 and the new remainder 62,and apply the division lemma to get

159 = 62 x 2 + 35

We consider the new divisor 62 and the new remainder 35,and apply the division lemma to get

62 = 35 x 1 + 27

We consider the new divisor 35 and the new remainder 27,and apply the division lemma to get

35 = 27 x 1 + 8

We consider the new divisor 27 and the new remainder 8,and apply the division lemma to get

27 = 8 x 3 + 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 380 and 601 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(27,8) = HCF(35,27) = HCF(62,35) = HCF(159,62) = HCF(221,159) = HCF(380,221) = HCF(601,380) .

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) .
