Given numbers are 402,969,649,590
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 402,969,649,590 is 421350270.
Find LCM of 402,969,649,590 with Prime Factorization
| 2 | 402, 969, 649, 590 |
| 3 | 201, 969, 649, 295 |
| 59 | 67, 323, 649, 295 |
| 67, 323, 11, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 59 x 67 x 323 x 11 x 5 = 421350270
Therefore, the lowest common multiple of 402,969,649,590 is 421350270.
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.
402 x 969 x 649 x 590 = 149157995580
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.
402 : 1, 2, 3, 6, 67, 134, 201, 402
969 : 1, 3, 17, 19, 51, 57, 323, 969
649 : 1, 11, 59, 649
590 : 1, 2, 5, 10, 59, 118, 295, 590
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,969,649,590, is 1.
Now, the common factors can be found like this.
402:2x 3x 67
969:3x 17x 19
649:11x 59
590:2x 5x 59
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 59 = 354
Therefore, the value for common factors is 354.
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 = 149157995580/(1x354)
LCM = 149157995580/354
LCM = 421350270
Thus, we can understand that the LCM of 402,969,649,590 is 421350270.
