Given numbers are 850,640,578,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 850,640,578,242 is 111900800.
Find LCM of 850,640,578,242 with Prime Factorization
| 2 | 850, 640, 578, 242 |
| 5 | 425, 320, 289, 121 |
| 17 | 85, 64, 289, 121 |
| 5, 64, 17, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 5 x 64 x 17 x 121 = 111900800
Therefore, the lowest common multiple of 850,640,578,242 is 111900800.
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.
850 x 640 x 578 x 242 = 76092544000
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.
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
578 : 1, 2, 17, 34, 289, 578
242 : 1, 2, 11, 22, 121, 242
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 850,640,578,242, is 2.
Now, the common factors can be found like this.
850:2x 5x 5x 17
640:2x 2x 2x 2x 2x 2x 2x 5
578:2x 17x 17
242:2x 11x 11
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 5x 17 = 340
Therefore, the value for common factors is 340.
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 = 76092544000/(2x340)
LCM = 76092544000/680
LCM = 111900800
Thus, we can understand that the LCM of 850,640,578,242 is 111900800.
