Given numbers are 453,370,888,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 453,370,888,861 is 192416280.
Find LCM of 453,370,888,861 with Prime Factorization
2 | 453, 370, 888, 861 |
3 | 453, 185, 444, 861 |
37 | 151, 185, 148, 287 |
151, 5, 4, 287 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 37 x 151 x 5 x 4 x 287 = 192416280
Therefore, the lowest common multiple of 453,370,888,861 is 192416280.
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.
453 x 370 x 888 x 861 = 128149242480
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.
453 : 1, 3, 151, 453
370 : 1, 2, 5, 10, 37, 74, 185, 370
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 453,370,888,861, is 1.
Now, the common factors can be found like this.
453:3x 151
370:2x 5x 37
888:2x 2x 2x 3x 37
861:3x 7x 41
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 3x 37 = 666
Therefore, the value for common factors is 666.
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 = 128149242480/(1x666)
LCM = 128149242480/666
LCM = 192416280
Thus, we can understand that the LCM of 453,370,888,861 is 192416280.
