HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 507, 285 i.e. 3 the largest integer that leaves a remainder zero for all numbers.

HCF of 507, 285 is 3 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 507, 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 507, 285 is 3.

HCF(507, 285) = 3

Highest common factor (HCF) of 507, 285 is 3.

Highest Common Factor of 507,285 using Euclid's algorithm

Highest Common Factor of 507,285 is 3

Step 1: Since 507 > 285, we apply the division lemma to 507 and 285, to get

507 = 285 x 1 + 222

Step 2: Since the reminder 285 ≠ 0, we apply division lemma to 222 and 285, to get

285 = 222 x 1 + 63

Step 3: We consider the new divisor 222 and the new remainder 63, and apply the division lemma to get

222 = 63 x 3 + 33

We consider the new divisor 63 and the new remainder 33,and apply the division lemma to get

63 = 33 x 1 + 30

We consider the new divisor 33 and the new remainder 30,and apply the division lemma to get

33 = 30 x 1 + 3

We consider the new divisor 30 and the new remainder 3,and apply the division lemma to get

30 = 3 x 10 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 507 and 285 is 3

Notice that 3 = HCF(30,3) = HCF(33,30) = HCF(63,33) = HCF(222,63) = HCF(285,222) = HCF(507,285) .
