HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 475, 625, 986 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 475, 625, 986 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 475, 625, 986 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 475, 625, 986 is 1.

HCF(475, 625, 986) = 1

Highest common factor (HCF) of 475, 625, 986 is 1.

Highest Common Factor of 475,625,986 using Euclid's algorithm

Highest Common Factor of 475,625,986 is 1

Step 1: Since 625 > 475, we apply the division lemma to 625 and 475, to get

625 = 475 x 1 + 150

Step 2: Since the reminder 475 ≠ 0, we apply division lemma to 150 and 475, to get

475 = 150 x 3 + 25

Step 3: We consider the new divisor 150 and the new remainder 25, and apply the division lemma to get

150 = 25 x 6 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 25, the HCF of 475 and 625 is 25

Notice that 25 = HCF(150,25) = HCF(475,150) = HCF(625,475) .

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

Step 1: Since 986 > 25, we apply the division lemma to 986 and 25, to get

986 = 25 x 39 + 11

Step 2: Since the reminder 25 ≠ 0, we apply division lemma to 11 and 25, to get

25 = 11 x 2 + 3

Step 3: We consider the new divisor 11 and the new remainder 3, and apply the division lemma to get

11 = 3 x 3 + 2

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 25 and 986 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(25,11) = HCF(986,25) .
