HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 315, 178, 939 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 315, 178, 939 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 315, 178, 939 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 315, 178, 939 is 1.

HCF(315, 178, 939) = 1

HCF of 315, 178, 939 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 315, 178, 939 is 1.

Highest Common Factor of 315,178,939 using Euclid's algorithm

Highest Common Factor of 315,178,939 is 1

Step 1: Since 315 > 178, we apply the division lemma to 315 and 178, to get

315 = 178 x 1 + 137

Step 2: Since the reminder 178 ≠ 0, we apply division lemma to 137 and 178, to get

178 = 137 x 1 + 41

Step 3: We consider the new divisor 137 and the new remainder 41, and apply the division lemma to get

137 = 41 x 3 + 14

We consider the new divisor 41 and the new remainder 14,and apply the division lemma to get

41 = 14 x 2 + 13

We consider the new divisor 14 and the new remainder 13,and apply the division lemma to get

14 = 13 x 1 + 1

We consider the new divisor 13 and the new remainder 1,and apply the division lemma to get

13 = 1 x 13 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 315 and 178 is 1

Notice that 1 = HCF(13,1) = HCF(14,13) = HCF(41,14) = HCF(137,41) = HCF(178,137) = HCF(315,178) .

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

Step 1: Since 939 > 1, we apply the division lemma to 939 and 1, to get

939 = 1 x 939 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 939 is 1

Notice that 1 = HCF(939,1) .
