HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 127, 485 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 127, 485 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 127, 485 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 127, 485 is 1.

HCF(127, 485) = 1

Highest common factor (HCF) of 127, 485 is 1.

Highest Common Factor of 127,485 using Euclid's algorithm

Highest Common Factor of 127,485 is 1

Step 1: Since 485 > 127, we apply the division lemma to 485 and 127, to get

485 = 127 x 3 + 104

Step 2: Since the reminder 127 ≠ 0, we apply division lemma to 104 and 127, to get

127 = 104 x 1 + 23

Step 3: We consider the new divisor 104 and the new remainder 23, and apply the division lemma to get

104 = 23 x 4 + 12

We consider the new divisor 23 and the new remainder 12,and apply the division lemma to get

23 = 12 x 1 + 11

We consider the new divisor 12 and the new remainder 11,and apply the division lemma to get

12 = 11 x 1 + 1

We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get

11 = 1 x 11 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 127 and 485 is 1

Notice that 1 = HCF(11,1) = HCF(12,11) = HCF(23,12) = HCF(104,23) = HCF(127,104) = HCF(485,127) .
