Find LCM of 678,975,535,754,619 with Prime Factorization
| 2 | 678, 975, 535, 754, 619 |
| 3 | 339, 975, 535, 377, 619 |
| 5 | 113, 325, 535, 377, 619 |
| 13 | 113, 65, 107, 377, 619 |
| 113, 5, 107, 29, 619 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 113 x 5 x 107 x 29 x 619 = 423238804950
Therefore, the lowest common multiple of 678,975,535,754,619 is 423238804950.
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.
678 x 975 x 535 x 754 x 619 = 165063133930500
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.
678 : 1, 2, 3, 6, 113, 226, 339, 678
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
535 : 1, 5, 107, 535
754 : 1, 2, 13, 26, 29, 58, 377, 754
619 : 1, 619
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 678,975,535,754,619, is 1.
Now, the common factors can be found like this.
678:2x 3x 113
975:3x 5x 5x 13
535:5x 107
754:2x 13x 29
619:619
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 5x 13 = 390
Therefore, the value for common factors is 390.
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 = 165063133930500/(1x390)
LCM = 165063133930500/390
LCM = 423238804950
Thus, we can understand that the LCM of 678,975,535,754,619 is 423238804950.
