Find LCM of 305,748,242,780,357 with Prime Factorization
2 | 305, 748, 242, 780, 357 |
2 | 305, 374, 121, 390, 357 |
3 | 305, 187, 121, 195, 357 |
5 | 305, 187, 121, 65, 119 |
11 | 61, 187, 121, 13, 119 |
17 | 61, 17, 11, 13, 119 |
61, 1, 11, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 17 x 61 x 1 x 11 x 13 x 7 = 685104420
Therefore, the lowest common multiple of 305,748,242,780,357 is 685104420.
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.
305 x 748 x 242 x 780 x 357 = 15373743184800
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.
305 : 1, 5, 61, 305
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
242 : 1, 2, 11, 22, 121, 242
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
357 : 1, 3, 7, 17, 21, 51, 119, 357
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 305,748,242,780,357, is 1.
Now, the common factors can be found like this.
305:5x 61
748:2x 2x 11x 17
242:2x 11x 11
780:2x 2x 3x 5x 13
357:3x 7x 17
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 5x 11x 17 = 22440
Therefore, the value for common factors is 22440.
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 = 15373743184800/(1x22440)
LCM = 15373743184800/22440
LCM = 685104420
Thus, we can understand that the LCM of 305,748,242,780,357 is 685104420.
