The LCM of 715,751,550,850 is 91284050.
Find LCM of 715,751,550,850 with Prime Factorization
| 2 | 715, 751, 550, 850 |
| 5 | 715, 751, 275, 425 |
| 5 | 143, 751, 55, 85 |
| 11 | 143, 751, 11, 17 |
| 13, 751, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 5 x 11 x 13 x 751 x 1 x 17 = 91284050
Therefore, the lowest common multiple of 715,751,550,850 is 91284050.
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.
715 x 751 x 550 x 850 = 251031137500
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
751 : 1, 751
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
850 : 1, 2, 5, 10, 17, 25, 34, 50, 85, 170, 425, 850
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,751,550,850, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
751:751
550:2x 5x 5x 11
850:2x 5x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 5x 11 = 2750
Therefore, the value for common factors is 2750.
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 = 251031137500/(1x2750)
LCM = 251031137500/2750
LCM = 91284050
Thus, we can understand that the LCM of 715,751,550,850 is 91284050.
