Given numbers are 905,640,714,962,807
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 905,640,714,962,807 is 5350866568320.
Find LCM of 905,640,714,962,807 with Prime Factorization
| 2 | 905, 640, 714, 962, 807 |
| 3 | 905, 320, 357, 481, 807 |
| 5 | 905, 320, 119, 481, 269 |
| 181, 64, 119, 481, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 181 x 64 x 119 x 481 x 269 = 5350866568320
Therefore, the lowest common multiple of 905,640,714,962,807 is 5350866568320.
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.
905 x 640 x 714 x 962 x 807 = 321051994099200
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.
905 : 1, 5, 181, 905
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
962 : 1, 2, 13, 26, 37, 74, 481, 962
807 : 1, 3, 269, 807
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 905,640,714,962,807, is 1.
Now, the common factors can be found like this.
905:5x 181
640:2x 2x 2x 2x 2x 2x 2x 5
714:2x 3x 7x 17
962:2x 13x 37
807:3x 269
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 5 = 60
Therefore, the value for common factors is 60.
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 = 321051994099200/(1x60)
LCM = 321051994099200/60
LCM = 5350866568320
Thus, we can understand that the LCM of 905,640,714,962,807 is 5350866568320.
