Given numbers are 155,454,868,993

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

The LCM of 155,454,868,993 is 978283740.

Find LCM of 155,454,868,993 with Prime Factorization

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

2 x 31 x 5 x 227 x 14 x 993 = 978283740

Therefore, the lowest common multiple of 155,454,868,993 is 978283740.

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.

155 x 454 x 868 x 993 = 60653591880

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.

155 : 1, 5, 31, 155

454 : 1, 2, 227, 454

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

993 : 1, 3, 331, 993

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,454,868,993, is 1.

Now, the common factors can be found like this.

155:5x 31

454:2x 227

868:2x 2x 7x 31

993:3x 331

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

2x 31 = 62

Therefore, the value for common factors is 62.

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 = 60653591880/(1x62)

LCM = 60653591880/62

LCM = 978283740

Thus, we can understand that the LCM of 155,454,868,993 is 978283740.
