Given numbers are 650,874,628,654,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 650,874,628,654,438 is 2129095070700.
Find LCM of 650,874,628,654,438 with Prime Factorization
| 2 | 650, 874, 628, 654, 438 |
| 3 | 325, 437, 314, 327, 219 |
| 325, 437, 314, 109, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 325 x 437 x 314 x 109 x 73 = 2129095070700
Therefore, the lowest common multiple of 650,874,628,654,438 is 2129095070700.
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.
650 x 874 x 628 x 654 x 438 = 102196563393600
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.
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
874 : 1, 2, 19, 23, 38, 46, 437, 874
628 : 1, 2, 4, 157, 314, 628
654 : 1, 2, 3, 6, 109, 218, 327, 654
438 : 1, 2, 3, 6, 73, 146, 219, 438
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 650,874,628,654,438, is 2.
Now, the common factors can be found like this.
650:2x 5x 5x 13
874:2x 19x 23
628:2x 2x 157
654:2x 3x 109
438:2x 3x 73
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 3 = 24
Therefore, the value for common factors is 24.
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 = 102196563393600/(2x24)
LCM = 102196563393600/48
LCM = 2129095070700
Thus, we can understand that the LCM of 650,874,628,654,438 is 2129095070700.
