HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 730, 512, 715 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 730, 512, 715 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 730, 512, 715 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 730, 512, 715 is 1.

HCF(730, 512, 715) = 1

Highest common factor (HCF) of 730, 512, 715 is 1.

Highest Common Factor of 730,512,715 using Euclid's algorithm

Highest Common Factor of 730,512,715 is 1

Step 1: Since 730 > 512, we apply the division lemma to 730 and 512, to get

730 = 512 x 1 + 218

Step 2: Since the reminder 512 ≠ 0, we apply division lemma to 218 and 512, to get

512 = 218 x 2 + 76

Step 3: We consider the new divisor 218 and the new remainder 76, and apply the division lemma to get

218 = 76 x 2 + 66

We consider the new divisor 76 and the new remainder 66,and apply the division lemma to get

76 = 66 x 1 + 10

We consider the new divisor 66 and the new remainder 10,and apply the division lemma to get

66 = 10 x 6 + 6

We consider the new divisor 10 and the new remainder 6,and apply the division lemma to get

10 = 6 x 1 + 4

We consider the new divisor 6 and the new remainder 4,and apply the division lemma to get

6 = 4 x 1 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 730 and 512 is 2

Notice that 2 = HCF(4,2) = HCF(6,4) = HCF(10,6) = HCF(66,10) = HCF(76,66) = HCF(218,76) = HCF(512,218) = HCF(730,512) .

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

Step 1: Since 715 > 2, we apply the division lemma to 715 and 2, to get

715 = 2 x 357 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 715 is 1

Notice that 1 = HCF(2,1) = HCF(715,2) .
