Find LCM of 639,518,172,966,590 with Prime Factorization
2 | 639, 518, 172, 966, 590 |
3 | 639, 259, 86, 483, 295 |
7 | 213, 259, 86, 161, 295 |
213, 37, 86, 23, 295 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 213 x 37 x 86 x 23 x 295 = 193142977020
Therefore, the lowest common multiple of 639,518,172,966,590 is 193142977020.
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.
639 x 518 x 172 x 966 x 590 = 32448020139360
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.
639 : 1, 3, 9, 71, 213, 639
518 : 1, 2, 7, 14, 37, 74, 259, 518
172 : 1, 2, 4, 43, 86, 172
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
590 : 1, 2, 5, 10, 59, 118, 295, 590
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,518,172,966,590, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
518:2x 7x 37
172:2x 2x 43
966:2x 3x 7x 23
590:2x 5x 59
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 3x 7 = 168
Therefore, the value for common factors is 168.
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 = 32448020139360/(1x168)
LCM = 32448020139360/168
LCM = 193142977020
Thus, we can understand that the LCM of 639,518,172,966,590 is 193142977020.
