HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 845, 478, 248 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 845, 478, 248 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 845, 478, 248 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 845, 478, 248 is 1.

HCF(845, 478, 248) = 1

Highest common factor (HCF) of 845, 478, 248 is 1.

Highest Common Factor of 845,478,248 using Euclid's algorithm

Highest Common Factor of 845,478,248 is 1

Step 1: Since 845 > 478, we apply the division lemma to 845 and 478, to get

845 = 478 x 1 + 367

Step 2: Since the reminder 478 ≠ 0, we apply division lemma to 367 and 478, to get

478 = 367 x 1 + 111

Step 3: We consider the new divisor 367 and the new remainder 111, and apply the division lemma to get

367 = 111 x 3 + 34

We consider the new divisor 111 and the new remainder 34,and apply the division lemma to get

111 = 34 x 3 + 9

We consider the new divisor 34 and the new remainder 9,and apply the division lemma to get

34 = 9 x 3 + 7

We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get

9 = 7 x 1 + 2

We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get

7 = 2 x 3 + 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 845 and 478 is 1

Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(34,9) = HCF(111,34) = HCF(367,111) = HCF(478,367) = HCF(845,478) .


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

Step 1: Since 248 > 1, we apply the division lemma to 248 and 1, to get

248 = 1 x 248 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 248 is 1

Notice that 1 = HCF(248,1) .
