Given numbers are 604,420,658,912
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 604,420,658,912 is 226536240.
Find LCM of 604,420,658,912 with Prime Factorization
| 2 | 604, 420, 658, 912 |
| 2 | 302, 210, 329, 456 |
| 3 | 151, 105, 329, 228 |
| 7 | 151, 35, 329, 76 |
| 151, 5, 47, 76 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 151 x 5 x 47 x 76 = 226536240
Therefore, the lowest common multiple of 604,420,658,912 is 226536240.
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.
604 x 420 x 658 x 912 = 152232353280
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.
604 : 1, 2, 4, 151, 302, 604
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
658 : 1, 2, 7, 14, 47, 94, 329, 658
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 604,420,658,912, is 2.
Now, the common factors can be found like this.
604:2x 2x 151
420:2x 2x 3x 5x 7
658:2x 7x 47
912:2x 2x 2x 2x 3x 19
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 3x 7 = 336
Therefore, the value for common factors is 336.
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 = 152232353280/(2x336)
LCM = 152232353280/672
LCM = 226536240
Thus, we can understand that the LCM of 604,420,658,912 is 226536240.
