Find LCM of 518,746,430,940,980 with Prime Factorization
2 | 518, 746, 430, 940, 980 |
2 | 259, 373, 215, 470, 490 |
5 | 259, 373, 215, 235, 245 |
7 | 259, 373, 43, 47, 49 |
37, 373, 43, 47, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 37 x 373 x 43 x 47 x 7 = 27333984580
Therefore, the lowest common multiple of 518,746,430,940,980 is 27333984580.
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.
518 x 746 x 430 x 940 x 980 = 153070313648000
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.
518 : 1, 2, 7, 14, 37, 74, 259, 518
746 : 1, 2, 373, 746
430 : 1, 2, 5, 10, 43, 86, 215, 430
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 518,746,430,940,980, is 2.
Now, the common factors can be found like this.
518:2x 7x 37
746:2x 373
430:2x 5x 43
940:2x 2x 5x 47
980:2x 2x 5x 7x 7
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 5x 5x 7 = 2800
Therefore, the value for common factors is 2800.
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 = 153070313648000/(2x2800)
LCM = 153070313648000/5600
LCM = 27333984580
Thus, we can understand that the LCM of 518,746,430,940,980 is 27333984580.
