HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 915, 787, 878 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 915, 787, 878 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, 787, 878 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, 787, 878 is 1.

HCF(915, 787, 878) = 1

HCF of 915, 787, 878 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 915, 787, 878 is 1.

Highest Common Factor of 915,787,878 using Euclid's algorithm

Highest Common Factor of 915,787,878 is 1

Step 1: Since 915 > 787, we apply the division lemma to 915 and 787, to get

915 = 787 x 1 + 128

Step 2: Since the reminder 787 ≠ 0, we apply division lemma to 128 and 787, to get

787 = 128 x 6 + 19

Step 3: We consider the new divisor 128 and the new remainder 19, and apply the division lemma to get

128 = 19 x 6 + 14

We consider the new divisor 19 and the new remainder 14,and apply the division lemma to get

19 = 14 x 1 + 5

We consider the new divisor 14 and the new remainder 5,and apply the division lemma to get

14 = 5 x 2 + 4

We consider the new divisor 5 and the new remainder 4,and apply the division lemma to get

5 = 4 x 1 + 1

We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get

4 = 1 x 4 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 915 and 787 is 1

Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(14,5) = HCF(19,14) = HCF(128,19) = HCF(787,128) = HCF(915,787) .

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

Step 1: Since 878 > 1, we apply the division lemma to 878 and 1, to get

878 = 1 x 878 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 878 is 1

Notice that 1 = HCF(878,1) .
