Given numbers are 220,904,352,437,978
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 220,904,352,437,978 is 42499263840.
Find LCM of 220,904,352,437,978 with Prime Factorization
| 2 | 220, 904, 352, 437, 978 |
| 2 | 110, 452, 176, 437, 489 |
| 2 | 55, 226, 88, 437, 489 |
| 11 | 55, 113, 44, 437, 489 |
| 5, 113, 4, 437, 489 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 5 x 113 x 4 x 437 x 489 = 42499263840
Therefore, the lowest common multiple of 220,904,352,437,978 is 42499263840.
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.
220 x 904 x 352 x 437 x 978 = 29919481743360
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
904 : 1, 2, 4, 8, 113, 226, 452, 904
352 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 88, 176, 352
437 : 1, 19, 23, 437
978 : 1, 2, 3, 6, 163, 326, 489, 978
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,904,352,437,978, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
904:2x 2x 2x 113
352:2x 2x 2x 2x 2x 11
437:19x 23
978:2x 3x 163
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 2x 2x 2x 11 = 704
Therefore, the value for common factors is 704.
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 = 29919481743360/(1x704)
LCM = 29919481743360/704
LCM = 42499263840
Thus, we can understand that the LCM of 220,904,352,437,978 is 42499263840.
