Given numbers are 740,991,201,720,990

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 740,991,201,720,990 is 19456976880.

Find LCM of 740,991,201,720,990 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 3 x 3 x 5 x 37 x 991 x 67 x 4 x 11 = 19456976880

Therefore, the lowest common multiple of 740,991,201,720,990 is 19456976880.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

740 x 991 x 201 x 720 x 990 = 105067675152000

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

991 : 1, 991

201 : 1, 3, 67, 201

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 740,991,201,720,990, is 1.

Now, the common factors can be found like this.

740:2x 2x 5x 37

991:991

201:3x 67

720:2x 2x 2x 2x 3x 3x 5

990:2x 3x 3x 5x 11

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 2x 3x 3x 3x 5x 5 = 5400

Therefore, the value for common factors is 5400.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 105067675152000/(1x5400)

LCM = 105067675152000/5400

LCM = 19456976880

Thus, we can understand that the LCM of 740,991,201,720,990 is 19456976880.
