HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 895, 580, 78 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 895, 580, 78 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 895, 580, 78 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 895, 580, 78 is 1.

HCF(895, 580, 78) = 1

Highest common factor (HCF) of 895, 580, 78 is 1.

Highest Common Factor of 895,580,78 using Euclid's algorithm

Highest Common Factor of 895,580,78 is 1

Step 1: Since 895 > 580, we apply the division lemma to 895 and 580, to get

895 = 580 x 1 + 315

Step 2: Since the reminder 580 ≠ 0, we apply division lemma to 315 and 580, to get

580 = 315 x 1 + 265

Step 3: We consider the new divisor 315 and the new remainder 265, and apply the division lemma to get

315 = 265 x 1 + 50

We consider the new divisor 265 and the new remainder 50,and apply the division lemma to get

265 = 50 x 5 + 15

We consider the new divisor 50 and the new remainder 15,and apply the division lemma to get

50 = 15 x 3 + 5

We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get

15 = 5 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 895 and 580 is 5

Notice that 5 = HCF(15,5) = HCF(50,15) = HCF(265,50) = HCF(315,265) = HCF(580,315) = HCF(895,580) .

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

Step 1: Since 78 > 5, we apply the division lemma to 78 and 5, to get

78 = 5 x 15 + 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 78 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(78,5) .
