Given numbers are 388,550,758,580
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 388,550,758,580 is 1172739700.
Find LCM of 388,550,758,580 with Prime Factorization
2 | 388, 550, 758, 580 |
2 | 194, 275, 379, 290 |
5 | 97, 275, 379, 145 |
97, 55, 379, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 97 x 55 x 379 x 29 = 1172739700
Therefore, the lowest common multiple of 388,550,758,580 is 1172739700.
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.
388 x 550 x 758 x 580 = 93819176000
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.
388 : 1, 2, 4, 97, 194, 388
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
758 : 1, 2, 379, 758
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 388,550,758,580, is 2.
Now, the common factors can be found like this.
388:2x 2x 97
550:2x 5x 5x 11
758:2x 379
580:2x 2x 5x 29
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 5 = 40
Therefore, the value for common factors is 40.
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 = 93819176000/(2x40)
LCM = 93819176000/80
LCM = 1172739700
Thus, we can understand that the LCM of 388,550,758,580 is 1172739700.
