Given numbers are 556,542,240,212
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,542,240,212 is 479149680.
Find LCM of 556,542,240,212 with Prime Factorization
| 2 | 556, 542, 240, 212 |
| 2 | 278, 271, 120, 106 |
| 139, 271, 60, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 139 x 271 x 60 x 53 = 479149680
Therefore, the lowest common multiple of 556,542,240,212 is 479149680.
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.
556 x 542 x 240 x 212 = 15332789760
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.
556 : 1, 2, 4, 139, 278, 556
542 : 1, 2, 271, 542
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
212 : 1, 2, 4, 53, 106, 212
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,542,240,212, is 2.
Now, the common factors can be found like this.
556:2x 2x 139
542:2x 271
240:2x 2x 2x 2x 3x 5
212:2x 2x 53
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 2 = 16
Therefore, the value for common factors is 16.
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 = 15332789760/(2x16)
LCM = 15332789760/32
LCM = 479149680
Thus, we can understand that the LCM of 556,542,240,212 is 479149680.
