Given numbers are 437,644,694,664,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,644,694,664,989 is 30307177096.
Find LCM of 437,644,694,664,989 with Prime Factorization
| 2 | 437, 644, 694, 664, 989 |
| 2 | 437, 322, 347, 332, 989 |
| 23 | 437, 161, 347, 166, 989 |
| 19, 7, 347, 166, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 19 x 7 x 347 x 166 x 43 = 30307177096
Therefore, the lowest common multiple of 437,644,694,664,989 is 30307177096.
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.
437 x 644 x 694 x 664 x 989 = 128259973470272
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.
437 : 1, 19, 23, 437
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
694 : 1, 2, 347, 694
664 : 1, 2, 4, 8, 83, 166, 332, 664
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,644,694,664,989, is 1.
Now, the common factors can be found like this.
437:19x 23
644:2x 2x 7x 23
694:2x 347
664:2x 2x 2x 83
989:23x 43
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 23x 23 = 4232
Therefore, the value for common factors is 4232.
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 = 128259973470272/(1x4232)
LCM = 128259973470272/4232
LCM = 30307177096
Thus, we can understand that the LCM of 437,644,694,664,989 is 30307177096.
