Given numbers are 640,364,545,847
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 640,364,545,847 is 768127360.
Find LCM of 640,364,545,847 with Prime Factorization
2 | 640, 364, 545, 847 |
2 | 320, 182, 545, 847 |
5 | 160, 91, 545, 847 |
7 | 32, 91, 109, 847 |
32, 13, 109, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 32 x 13 x 109 x 121 = 768127360
Therefore, the lowest common multiple of 640,364,545,847 is 768127360.
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.
640 x 364 x 545 x 847 = 107537830400
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.
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364
545 : 1, 5, 109, 545
847 : 1, 7, 11, 77, 121, 847
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 640,364,545,847, is 1.
Now, the common factors can be found like this.
640:2x 2x 2x 2x 2x 2x 2x 5
364:2x 2x 7x 13
545:5x 109
847:7x 11x 11
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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 107537830400/(1x140)
LCM = 107537830400/140
LCM = 768127360
Thus, we can understand that the LCM of 640,364,545,847 is 768127360.
