HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 759, 445, 490 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 759, 445, 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 759, 445, 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 759, 445, 490 is 1.

HCF(759, 445, 490) = 1

HCF of 759, 445, 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 759, 445, 490 is 1.

Highest Common Factor of 759,445,490 using Euclid's algorithm

Highest Common Factor of 759,445,490 is 1

Step 1: Since 759 > 445, we apply the division lemma to 759 and 445, to get

759 = 445 x 1 + 314

Step 2: Since the reminder 445 ≠ 0, we apply division lemma to 314 and 445, to get

445 = 314 x 1 + 131

Step 3: We consider the new divisor 314 and the new remainder 131, and apply the division lemma to get

314 = 131 x 2 + 52

We consider the new divisor 131 and the new remainder 52,and apply the division lemma to get

131 = 52 x 2 + 27

We consider the new divisor 52 and the new remainder 27,and apply the division lemma to get

52 = 27 x 1 + 25

We consider the new divisor 27 and the new remainder 25,and apply the division lemma to get

27 = 25 x 1 + 2

We consider the new divisor 25 and the new remainder 2,and apply the division lemma to get

25 = 2 x 12 + 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 759 and 445 is 1

Notice that 1 = HCF(2,1) = HCF(25,2) = HCF(27,25) = HCF(52,27) = HCF(131,52) = HCF(314,131) = HCF(445,314) = HCF(759,445) .

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) .
