HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 416, 818, 275 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 416, 818, 275 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 416, 818, 275 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 416, 818, 275 is 1.

HCF(416, 818, 275) = 1

Highest common factor (HCF) of 416, 818, 275 is 1.

Highest Common Factor of 416,818,275 using Euclid's algorithm

Highest Common Factor of 416,818,275 is 1

Step 1: Since 818 > 416, we apply the division lemma to 818 and 416, to get

818 = 416 x 1 + 402

Step 2: Since the reminder 416 ≠ 0, we apply division lemma to 402 and 416, to get

416 = 402 x 1 + 14

Step 3: We consider the new divisor 402 and the new remainder 14, and apply the division lemma to get

402 = 14 x 28 + 10

We consider the new divisor 14 and the new remainder 10,and apply the division lemma to get

14 = 10 x 1 + 4

We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get

10 = 4 x 2 + 2

We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get

4 = 2 x 2 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 416 and 818 is 2

Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(402,14) = HCF(416,402) = HCF(818,416) .

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

Step 1: Since 275 > 2, we apply the division lemma to 275 and 2, to get

275 = 2 x 137 + 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 275 is 1

Notice that 1 = HCF(2,1) = HCF(275,2) .
