Given numbers are 542,991,494,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 542,991,494,870 is 57711073290.
Find LCM of 542,991,494,870 with Prime Factorization
| 2 | 542, 991, 494, 870 |
| 271, 991, 247, 435 |
Multiply the prime numbers at the bottom and the left side.
2 x 271 x 991 x 247 x 435 = 57711073290
Therefore, the lowest common multiple of 542,991,494,870 is 57711073290.
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.
542 x 991 x 494 x 870 = 230844293160
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.
542 : 1, 2, 271, 542
991 : 1, 991
494 : 1, 2, 13, 19, 26, 38, 247, 494
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 542,991,494,870, is 1.
Now, the common factors can be found like this.
542:2x 271
991:991
494:2x 13x 19
870:2x 3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 230844293160/(1x4)
LCM = 230844293160/4
LCM = 57711073290
Thus, we can understand that the LCM of 542,991,494,870 is 57711073290.
