HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 505, 730, 758 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 505, 730, 758 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 505, 730, 758 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 505, 730, 758 is 1.

HCF(505, 730, 758) = 1

HCF of 505, 730, 758 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 505, 730, 758 is 1.

Highest Common Factor of 505,730,758 using Euclid's algorithm

Highest Common Factor of 505,730,758 is 1

Step 1: Since 730 > 505, we apply the division lemma to 730 and 505, to get

730 = 505 x 1 + 225

Step 2: Since the reminder 505 ≠ 0, we apply division lemma to 225 and 505, to get

505 = 225 x 2 + 55

Step 3: We consider the new divisor 225 and the new remainder 55, and apply the division lemma to get

225 = 55 x 4 + 5

We consider the new divisor 55 and the new remainder 5, and apply the division lemma to get

55 = 5 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 505 and 730 is 5

Notice that 5 = HCF(55,5) = HCF(225,55) = HCF(505,225) = HCF(730,505) .

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

Step 1: Since 758 > 5, we apply the division lemma to 758 and 5, to get

758 = 5 x 151 + 3

Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get

5 = 3 x 1 + 2

Step 3: 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 5 and 758 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(758,5) .
