HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 475, 932, 28 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 475, 932, 28 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, 932, 28 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, 932, 28 is 1.

HCF(475, 932, 28) = 1

Highest common factor (HCF) of 475, 932, 28 is 1.

Highest Common Factor of 475,932,28 using Euclid's algorithm

Highest Common Factor of 475,932,28 is 1

Step 1: Since 932 > 475, we apply the division lemma to 932 and 475, to get

932 = 475 x 1 + 457

Step 2: Since the reminder 475 ≠ 0, we apply division lemma to 457 and 475, to get

475 = 457 x 1 + 18

Step 3: We consider the new divisor 457 and the new remainder 18, and apply the division lemma to get

457 = 18 x 25 + 7

We consider the new divisor 18 and the new remainder 7,and apply the division lemma to get

18 = 7 x 2 + 4

We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get

7 = 4 x 1 + 3

We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get

4 = 3 x 1 + 1

We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get

3 = 1 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 475 and 932 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(18,7) = HCF(457,18) = HCF(475,457) = HCF(932,475) .

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

Step 1: Since 28 > 1, we apply the division lemma to 28 and 1, to get

28 = 1 x 28 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 28 is 1

Notice that 1 = HCF(28,1) .
