HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 753, 530, 349 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 753, 530, 349 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 753, 530, 349 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 753, 530, 349 is 1.

HCF(753, 530, 349) = 1

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

HCF of:

Highest common factor (HCF) of 753, 530, 349 is 1.

Highest Common Factor of 753,530,349 using Euclid's algorithm

Highest Common Factor of 753,530,349 is 1

Step 1: Since 753 > 530, we apply the division lemma to 753 and 530, to get

753 = 530 x 1 + 223

Step 2: Since the reminder 530 ≠ 0, we apply division lemma to 223 and 530, to get

530 = 223 x 2 + 84

Step 3: We consider the new divisor 223 and the new remainder 84, and apply the division lemma to get

223 = 84 x 2 + 55

We consider the new divisor 84 and the new remainder 55,and apply the division lemma to get

84 = 55 x 1 + 29

We consider the new divisor 55 and the new remainder 29,and apply the division lemma to get

55 = 29 x 1 + 26

We consider the new divisor 29 and the new remainder 26,and apply the division lemma to get

29 = 26 x 1 + 3

We consider the new divisor 26 and the new remainder 3,and apply the division lemma to get

26 = 3 x 8 + 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 753 and 530 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(26,3) = HCF(29,26) = HCF(55,29) = HCF(84,55) = HCF(223,84) = HCF(530,223) = HCF(753,530) .

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

Step 1: Since 349 > 1, we apply the division lemma to 349 and 1, to get

349 = 1 x 349 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 349 is 1

Notice that 1 = HCF(349,1) .
