HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 915, 675, 302 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 915, 675, 302 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 915, 675, 302 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 915, 675, 302 is 1.

HCF(915, 675, 302) = 1

Highest common factor (HCF) of 915, 675, 302 is 1.

Highest Common Factor of 915,675,302 using Euclid's algorithm

Highest Common Factor of 915,675,302 is 1

Step 1: Since 915 > 675, we apply the division lemma to 915 and 675, to get

915 = 675 x 1 + 240

Step 2: Since the reminder 675 ≠ 0, we apply division lemma to 240 and 675, to get

675 = 240 x 2 + 195

Step 3: We consider the new divisor 240 and the new remainder 195, and apply the division lemma to get

240 = 195 x 1 + 45

We consider the new divisor 195 and the new remainder 45,and apply the division lemma to get

195 = 45 x 4 + 15

We consider the new divisor 45 and the new remainder 15,and apply the division lemma to get

45 = 15 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 15, the HCF of 915 and 675 is 15

Notice that 15 = HCF(45,15) = HCF(195,45) = HCF(240,195) = HCF(675,240) = HCF(915,675) .

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

Step 1: Since 302 > 15, we apply the division lemma to 302 and 15, to get

302 = 15 x 20 + 2

Step 2: Since the reminder 15 ≠ 0, we apply division lemma to 2 and 15, to get

15 = 2 x 7 + 1

Step 3: 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 15 and 302 is 1

Notice that 1 = HCF(2,1) = HCF(15,2) = HCF(302,15) .
