The LCM of 757,387,605,100,688 is 14179215600.
Find LCM of 757,387,605,100,688 with Prime Factorization
| 2 | 757, 387, 605, 100, 688 |
| 2 | 757, 387, 605, 50, 344 |
| 5 | 757, 387, 605, 25, 172 |
| 43 | 757, 387, 121, 5, 172 |
| 757, 9, 121, 5, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 43 x 757 x 9 x 121 x 5 x 4 = 14179215600
Therefore, the lowest common multiple of 757,387,605,100,688 is 14179215600.
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.
757 x 387 x 605 x 100 x 688 = 12194125416000
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.
757 : 1, 757
387 : 1, 3, 9, 43, 129, 387
605 : 1, 5, 11, 55, 121, 605
100 : 1, 2, 4, 5, 10, 20, 25, 50, 100
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 757,387,605,100,688, is 1.
Now, the common factors can be found like this.
757:757
387:3x 3x 43
605:5x 11x 11
100:2x 2x 5x 5
688:2x 2x 2x 2x 43
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 43 = 860
Therefore, the value for common factors is 860.
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 = 12194125416000/(1x860)
LCM = 12194125416000/860
LCM = 14179215600
Thus, we can understand that the LCM of 757,387,605,100,688 is 14179215600.
