Given numbers are 254,550,987,902,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 254,550,987,902,380 is 107411558100.
Find LCM of 254,550,987,902,380 with Prime Factorization
| 2 | 254, 550, 987, 902, 380 |
| 5 | 127, 275, 987, 451, 190 |
| 11 | 127, 55, 987, 451, 38 |
| 127, 5, 987, 41, 38 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 127 x 5 x 987 x 41 x 38 = 107411558100
Therefore, the lowest common multiple of 254,550,987,902,380 is 107411558100.
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.
254 x 550 x 987 x 902 x 380 = 47261085564000
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.
254 : 1, 2, 127, 254
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
987 : 1, 3, 7, 21, 47, 141, 329, 987
902 : 1, 2, 11, 22, 41, 82, 451, 902
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 254,550,987,902,380, is 1.
Now, the common factors can be found like this.
254:2x 127
550:2x 5x 5x 11
987:3x 7x 47
902:2x 11x 41
380:2x 2x 5x 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 5x 11 = 440
Therefore, the value for common factors is 440.
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 = 47261085564000/(1x440)
LCM = 47261085564000/440
LCM = 107411558100
Thus, we can understand that the LCM of 254,550,987,902,380 is 107411558100.
