HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 378, 3940, 2825 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 378, 3940, 2825 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 378, 3940, 2825 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 378, 3940, 2825 is 1.

HCF(378, 3940, 2825) = 1

Highest common factor (HCF) of 378, 3940, 2825 is 1.

Highest Common Factor of 378,3940,2825 using Euclid's algorithm

Highest Common Factor of 378,3940,2825 is 1

Step 1: Since 3940 > 378, we apply the division lemma to 3940 and 378, to get

3940 = 378 x 10 + 160

Step 2: Since the reminder 378 ≠ 0, we apply division lemma to 160 and 378, to get

378 = 160 x 2 + 58

Step 3: We consider the new divisor 160 and the new remainder 58, and apply the division lemma to get

160 = 58 x 2 + 44

We consider the new divisor 58 and the new remainder 44,and apply the division lemma to get

58 = 44 x 1 + 14

We consider the new divisor 44 and the new remainder 14,and apply the division lemma to get

44 = 14 x 3 + 2

We consider the new divisor 14 and the new remainder 2,and apply the division lemma to get

14 = 2 x 7 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 378 and 3940 is 2

Notice that 2 = HCF(14,2) = HCF(44,14) = HCF(58,44) = HCF(160,58) = HCF(378,160) = HCF(3940,378) .

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

Step 1: Since 2825 > 2, we apply the division lemma to 2825 and 2, to get

2825 = 2 x 1412 + 1

Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 2825 is 1

Notice that 1 = HCF(2,1) = HCF(2825,2) .
