Given numbers are 973,726,570,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 973,726,570,780 is 1744803060.
Find LCM of 973,726,570,780 with Prime Factorization
| 2 | 973, 726, 570, 780 |
| 3 | 973, 363, 285, 390 |
| 5 | 973, 121, 95, 130 |
| 973, 121, 19, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 973 x 121 x 19 x 26 = 1744803060
Therefore, the lowest common multiple of 973,726,570,780 is 1744803060.
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.
973 x 726 x 570 x 780 = 314064550800
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.
973 : 1, 7, 139, 973
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 973,726,570,780, is 1.
Now, the common factors can be found like this.
973:7x 139
726:2x 3x 11x 11
570:2x 3x 5x 19
780:2x 2x 3x 5x 13
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 3x 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 314064550800/(1x180)
LCM = 314064550800/180
LCM = 1744803060
Thus, we can understand that the LCM of 973,726,570,780 is 1744803060.
