The LCM of 754,780,316,915 is 109005780.
Find LCM of 754,780,316,915 with Prime Factorization
| 2 | 754, 780, 316, 915 |
| 2 | 377, 390, 158, 915 |
| 3 | 377, 195, 79, 915 |
| 5 | 377, 65, 79, 305 |
| 13 | 377, 13, 79, 61 |
| 29, 1, 79, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 29 x 1 x 79 x 61 = 109005780
Therefore, the lowest common multiple of 754,780,316,915 is 109005780.
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.
754 x 780 x 316 x 915 = 170049016800
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.
754 : 1, 2, 13, 26, 29, 58, 377, 754
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
316 : 1, 2, 4, 79, 158, 316
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 754,780,316,915, is 1.
Now, the common factors can be found like this.
754:2x 13x 29
780:2x 2x 3x 5x 13
316:2x 2x 79
915:3x 5x 61
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 2x 3x 5x 13 = 1560
Therefore, the value for common factors is 1560.
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 = 170049016800/(1x1560)
LCM = 170049016800/1560
LCM = 109005780
Thus, we can understand that the LCM of 754,780,316,915 is 109005780.
