Given numbers are 741,812,795,978,840

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

The LCM of 741,812,795,978,840 is 51980171880.

Find LCM of 741,812,795,978,840 with Prime Factorization

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

2 x 2 x 3 x 5 x 7 x 247 x 29 x 53 x 163 x 2 = 51980171880

Therefore, the lowest common multiple of 741,812,795,978,840 is 51980171880.

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.

741 x 812 x 795 x 978 x 840 = 392970099412800

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.

741 : 1, 3, 13, 19, 39, 57, 247, 741

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

795 : 1, 3, 5, 15, 53, 159, 265, 795

978 : 1, 2, 3, 6, 163, 326, 489, 978

840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,812,795,978,840, is 1.

Now, the common factors can be found like this.

741:3x 13x 19

812:2x 2x 7x 29

795:3x 5x 53

978:2x 3x 163

840:2x 2x 2x 3x 5x 7

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 7 = 7560

Therefore, the value for common factors is 7560.

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 = 392970099412800/(1x7560)

LCM = 392970099412800/7560

LCM = 51980171880

Thus, we can understand that the LCM of 741,812,795,978,840 is 51980171880.
