HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 743, 486, 336 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 743, 486, 336 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 743, 486, 336 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 743, 486, 336 is 1.

HCF(743, 486, 336) = 1

Highest common factor (HCF) of 743, 486, 336 is 1.

Highest Common Factor of 743,486,336 using Euclid's algorithm

Highest Common Factor of 743,486,336 is 1

Step 1: Since 743 > 486, we apply the division lemma to 743 and 486, to get

743 = 486 x 1 + 257

Step 2: Since the reminder 486 ≠ 0, we apply division lemma to 257 and 486, to get

486 = 257 x 1 + 229

Step 3: We consider the new divisor 257 and the new remainder 229, and apply the division lemma to get

257 = 229 x 1 + 28

We consider the new divisor 229 and the new remainder 28,and apply the division lemma to get

229 = 28 x 8 + 5

We consider the new divisor 28 and the new remainder 5,and apply the division lemma to get

28 = 5 x 5 + 3

We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get

5 = 3 x 1 + 2

We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get

3 = 2 x 1 + 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 743 and 486 is 1

Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(28,5) = HCF(229,28) = HCF(257,229) = HCF(486,257) = HCF(743,486) .

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

Step 1: Since 336 > 1, we apply the division lemma to 336 and 1, to get

336 = 1 x 336 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 336 is 1

Notice that 1 = HCF(336,1) .
