HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 535, 912, 285 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 535, 912, 285 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 535, 912, 285 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 535, 912, 285 is 1.

HCF(535, 912, 285) = 1

Highest common factor (HCF) of 535, 912, 285 is 1.

Highest Common Factor of 535,912,285 using Euclid's algorithm

Highest Common Factor of 535,912,285 is 1

Step 1: Since 912 > 535, we apply the division lemma to 912 and 535, to get

912 = 535 x 1 + 377

Step 2: Since the reminder 535 ≠ 0, we apply division lemma to 377 and 535, to get

535 = 377 x 1 + 158

Step 3: We consider the new divisor 377 and the new remainder 158, and apply the division lemma to get

377 = 158 x 2 + 61

We consider the new divisor 158 and the new remainder 61,and apply the division lemma to get

158 = 61 x 2 + 36

We consider the new divisor 61 and the new remainder 36,and apply the division lemma to get

61 = 36 x 1 + 25

We consider the new divisor 36 and the new remainder 25,and apply the division lemma to get

36 = 25 x 1 + 11

We consider the new divisor 25 and the new remainder 11,and apply the division lemma to get

25 = 11 x 2 + 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 535 and 912 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(11,3) = HCF(25,11) = HCF(36,25) = HCF(61,36) = HCF(158,61) = HCF(377,158) = HCF(535,377) = HCF(912,535) .

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

Step 1: Since 285 > 1, we apply the division lemma to 285 and 1, to get

285 = 1 x 285 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 285 is 1

Notice that 1 = HCF(285,1) .
