Given numbers are 409,972,762,254
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 409,972,762,254 is 50488596.
Find LCM of 409,972,762,254 with Prime Factorization
| 2 | 409, 972, 762, 254 |
| 3 | 409, 486, 381, 127 |
| 127 | 409, 162, 127, 127 |
| 409, 162, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 127 x 409 x 162 x 1 x 1 = 50488596
Therefore, the lowest common multiple of 409,972,762,254 is 50488596.
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.
409 x 972 x 762 x 254 = 76944620304
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.
409 : 1, 409
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
762 : 1, 2, 3, 6, 127, 254, 381, 762
254 : 1, 2, 127, 254
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,972,762,254, is 1.
Now, the common factors can be found like this.
409:409
972:2x 2x 3x 3x 3x 3x 3
762:2x 3x 127
254:2x 127
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 127 = 1524
Therefore, the value for common factors is 1524.
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 = 76944620304/(1x1524)
LCM = 76944620304/1524
LCM = 50488596
Thus, we can understand that the LCM of 409,972,762,254 is 50488596.
