Given numbers are 902,416,921,616
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 902,416,921,616 is 1209560352.
Find LCM of 902,416,921,616 with Prime Factorization
| 2 | 902, 416, 921, 616 |
| 2 | 451, 208, 921, 308 |
| 2 | 451, 104, 921, 154 |
| 11 | 451, 52, 921, 77 |
| 41, 52, 921, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 41 x 52 x 921 x 7 = 1209560352
Therefore, the lowest common multiple of 902,416,921,616 is 1209560352.
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.
902 x 416 x 921 x 616 = 212882621952
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
921 : 1, 3, 307, 921
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,416,921,616, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
416:2x 2x 2x 2x 2x 13
921:3x 307
616:2x 2x 2x 7x 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 2x 2x 11 = 176
Therefore, the value for common factors is 176.
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 = 212882621952/(1x176)
LCM = 212882621952/176
LCM = 1209560352
Thus, we can understand that the LCM of 902,416,921,616 is 1209560352.
