HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 743, 489, 149, 380 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 743, 489, 149, 380 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, 489, 149, 380 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, 489, 149, 380 is 1.

HCF(743, 489, 149, 380) = 1

Highest common factor (HCF) of 743, 489, 149, 380 is 1.

Highest Common Factor of 743,489,149,380 using Euclid's algorithm

Highest Common Factor of 743,489,149,380 is 1

Step 1: Since 743 > 489, we apply the division lemma to 743 and 489, to get

743 = 489 x 1 + 254

Step 2: Since the reminder 489 ≠ 0, we apply division lemma to 254 and 489, to get

489 = 254 x 1 + 235

Step 3: We consider the new divisor 254 and the new remainder 235, and apply the division lemma to get

254 = 235 x 1 + 19

We consider the new divisor 235 and the new remainder 19,and apply the division lemma to get

235 = 19 x 12 + 7

We consider the new divisor 19 and the new remainder 7,and apply the division lemma to get

19 = 7 x 2 + 5

We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get

7 = 5 x 1 + 2

We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get

5 = 2 x 2 + 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 489 is 1

Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(19,7) = HCF(235,19) = HCF(254,235) = HCF(489,254) = HCF(743,489) .

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

Step 1: Since 149 > 1, we apply the division lemma to 149 and 1, to get

149 = 1 x 149 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 149 is 1

Notice that 1 = HCF(149,1) .

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

Step 1: Since 380 > 1, we apply the division lemma to 380 and 1, to get

380 = 1 x 380 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 380 is 1

Notice that 1 = HCF(380,1) .
