HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 415, 646, 902, 395 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 415, 646, 902, 395 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, 646, 902, 395 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, 646, 902, 395 is 1.

HCF(415, 646, 902, 395) = 1

Highest common factor (HCF) of 415, 646, 902, 395 is 1.

Highest Common Factor of 415,646,902,395 using Euclid's algorithm

Highest Common Factor of 415,646,902,395 is 1

Step 1: Since 646 > 415, we apply the division lemma to 646 and 415, to get

646 = 415 x 1 + 231

Step 2: Since the reminder 415 ≠ 0, we apply division lemma to 231 and 415, to get

415 = 231 x 1 + 184

Step 3: We consider the new divisor 231 and the new remainder 184, and apply the division lemma to get

231 = 184 x 1 + 47

We consider the new divisor 184 and the new remainder 47,and apply the division lemma to get

184 = 47 x 3 + 43

We consider the new divisor 47 and the new remainder 43,and apply the division lemma to get

47 = 43 x 1 + 4

We consider the new divisor 43 and the new remainder 4,and apply the division lemma to get

43 = 4 x 10 + 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 415 and 646 is 1

Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(43,4) = HCF(47,43) = HCF(184,47) = HCF(231,184) = HCF(415,231) = HCF(646,415) .


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

Step 1: Since 902 > 1, we apply the division lemma to 902 and 1, to get

902 = 1 x 902 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 902 is 1

Notice that 1 = HCF(902,1) .


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

Step 1: Since 395 > 1, we apply the division lemma to 395 and 1, to get

395 = 1 x 395 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 395 is 1

Notice that 1 = HCF(395,1) .
