Given numbers are 470,578,690,894,556
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 470,578,690,894,556 is 388218167940.
Find LCM of 470,578,690,894,556 with Prime Factorization
| 2 | 470, 578, 690, 894, 556 |
| 3 | 235, 289, 345, 447, 278 |
| 5 | 235, 289, 115, 149, 278 |
| 47, 289, 23, 149, 278 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 47 x 289 x 23 x 149 x 278 = 388218167940
Therefore, the lowest common multiple of 470,578,690,894,556 is 388218167940.
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.
470 x 578 x 690 x 894 x 556 = 93172360305600
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.
470 : 1, 2, 5, 10, 47, 94, 235, 470
578 : 1, 2, 17, 34, 289, 578
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
894 : 1, 2, 3, 6, 149, 298, 447, 894
556 : 1, 2, 4, 139, 278, 556
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 470,578,690,894,556, is 2.
Now, the common factors can be found like this.
470:2x 5x 47
578:2x 17x 17
690:2x 3x 5x 23
894:2x 3x 149
556:2x 2x 139
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 5 = 120
Therefore, the value for common factors is 120.
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 = 93172360305600/(2x120)
LCM = 93172360305600/240
LCM = 388218167940
Thus, we can understand that the LCM of 470,578,690,894,556 is 388218167940.
