Given numbers are 720,754,562,156
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 720,754,562,156 is 76274640.
Find LCM of 720,754,562,156 with Prime Factorization
| 2 | 720, 754, 562, 156 |
| 2 | 360, 377, 281, 78 |
| 3 | 180, 377, 281, 39 |
| 13 | 60, 377, 281, 13 |
| 60, 29, 281, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 60 x 29 x 281 x 1 = 76274640
Therefore, the lowest common multiple of 720,754,562,156 is 76274640.
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.
720 x 754 x 562 x 156 = 47595375360
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.
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
754 : 1, 2, 13, 26, 29, 58, 377, 754
562 : 1, 2, 281, 562
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,754,562,156, is 2.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
754:2x 13x 29
562:2x 281
156:2x 2x 3x 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 2x 3x 13 = 312
Therefore, the value for common factors is 312.
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 = 47595375360/(2x312)
LCM = 47595375360/624
LCM = 76274640
Thus, we can understand that the LCM of 720,754,562,156 is 76274640.
