Given numbers are 278,975,661,374
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,975,661,374 is 33503677350.
Find LCM of 278,975,661,374 with Prime Factorization
| 2 | 278, 975, 661, 374 |
| 139, 975, 661, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 139 x 975 x 661 x 187 = 33503677350
Therefore, the lowest common multiple of 278,975,661,374 is 33503677350.
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.
278 x 975 x 661 x 374 = 67007354700
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.
278 : 1, 2, 139, 278
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
661 : 1, 661
374 : 1, 2, 11, 17, 22, 34, 187, 374
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,975,661,374, is 1.
Now, the common factors can be found like this.
278:2x 139
975:3x 5x 5x 13
661:661
374:2x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 67007354700/(1x2)
LCM = 67007354700/2
LCM = 33503677350
Thus, we can understand that the LCM of 278,975,661,374 is 33503677350.
