Find LCM of 278,102,399,620,960 with Prime Factorization
2 | 278, 102, 399, 620, 960 |
2 | 139, 51, 399, 310, 480 |
3 | 139, 51, 399, 155, 240 |
5 | 139, 17, 133, 155, 80 |
139, 17, 133, 31, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 139 x 17 x 133 x 31 x 16 = 9352943040
Therefore, the lowest common multiple of 278,102,399,620,960 is 9352943040.
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.
278 x 102 x 399 x 620 x 960 = 6734118988800
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.
278 : 1, 2, 139, 278
102 : 1, 2, 3, 6, 17, 34, 51, 102
399 : 1, 3, 7, 19, 21, 57, 133, 399
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,102,399,620,960, is 1.
Now, the common factors can be found like this.
278:2x 139
102:2x 3x 17
399:3x 7x 19
620:2x 2x 5x 31
960:2x 2x 2x 2x 2x 2x 3x 5
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 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 6734118988800/(1x720)
LCM = 6734118988800/720
LCM = 9352943040
Thus, we can understand that the LCM of 278,102,399,620,960 is 9352943040.
