Given numbers are 502,980,988,240
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 502,980,988,240 is 729084720.
Find LCM of 502,980,988,240 with Prime Factorization
| 2 | 502, 980, 988, 240 |
| 2 | 251, 490, 494, 120 |
| 5 | 251, 245, 247, 60 |
| 251, 49, 247, 12 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 251 x 49 x 247 x 12 = 729084720
Therefore, the lowest common multiple of 502,980,988,240 is 729084720.
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.
502 x 980 x 988 x 240 = 116653555200
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.
502 : 1, 2, 251, 502
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 502,980,988,240, is 2.
Now, the common factors can be found like this.
502:2x 251
980:2x 2x 5x 7x 7
988:2x 2x 13x 19
240:2x 2x 2x 2x 3x 5
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 2x 5 = 80
Therefore, the value for common factors is 80.
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 = 116653555200/(2x80)
LCM = 116653555200/160
LCM = 729084720
Thus, we can understand that the LCM of 502,980,988,240 is 729084720.
