HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 415, 257, 633 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 415, 257, 633 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 415, 257, 633 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 415, 257, 633 is 1.

HCF(415, 257, 633) = 1

Highest common factor (HCF) of 415, 257, 633 is 1.

Highest Common Factor of 415,257,633 using Euclid's algorithm

Highest Common Factor of 415,257,633 is 1

Step 1: Since 415 > 257, we apply the division lemma to 415 and 257, to get

415 = 257 x 1 + 158

Step 2: Since the reminder 257 ≠ 0, we apply division lemma to 158 and 257, to get

257 = 158 x 1 + 99

Step 3: We consider the new divisor 158 and the new remainder 99, and apply the division lemma to get

158 = 99 x 1 + 59

We consider the new divisor 99 and the new remainder 59,and apply the division lemma to get

99 = 59 x 1 + 40

We consider the new divisor 59 and the new remainder 40,and apply the division lemma to get

59 = 40 x 1 + 19

We consider the new divisor 40 and the new remainder 19,and apply the division lemma to get

40 = 19 x 2 + 2

We consider the new divisor 19 and the new remainder 2,and apply the division lemma to get

19 = 2 x 9 + 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 415 and 257 is 1

Notice that 1 = HCF(2,1) = HCF(19,2) = HCF(40,19) = HCF(59,40) = HCF(99,59) = HCF(158,99) = HCF(257,158) = HCF(415,257) .


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

Step 1: Since 633 > 1, we apply the division lemma to 633 and 1, to get

633 = 1 x 633 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 633 is 1

Notice that 1 = HCF(633,1) .
