The LCM of 437,972,872,620 is 14352775560.
Find LCM of 437,972,872,620 with Prime Factorization
| 2 | 437, 972, 872, 620 |
| 2 | 437, 486, 436, 310 |
| 437, 243, 218, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 437 x 243 x 218 x 155 = 14352775560
Therefore, the lowest common multiple of 437,972,872,620 is 14352775560.
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 972 x 872 x 620 = 229644408960
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
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
872 : 1, 2, 4, 8, 109, 218, 436, 872
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,972,872,620, is 1.
Now, the common factors can be found like this.
437:19x 23
972:2x 2x 3x 3x 3x 3x 3
872:2x 2x 2x 109
620:2x 2x 5x 31
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 2 = 16
Therefore, the value for common factors is 16.
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 = 229644408960/(1x16)
LCM = 229644408960/16
LCM = 14352775560
Thus, we can understand that the LCM of 437,972,872,620 is 14352775560.
