Given numbers are 914,160,420,572
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 914,160,420,572 is 219579360.
Find LCM of 914,160,420,572 with Prime Factorization
2 | 914, 160, 420, 572 |
2 | 457, 80, 210, 286 |
5 | 457, 40, 105, 143 |
457, 8, 21, 143 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 457 x 8 x 21 x 143 = 219579360
Therefore, the lowest common multiple of 914,160,420,572 is 219579360.
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.
914 x 160 x 420 x 572 = 35132697600
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.
914 : 1, 2, 457, 914
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 914,160,420,572, is 2.
Now, the common factors can be found like this.
914:2x 457
160:2x 2x 2x 2x 2x 5
420:2x 2x 3x 5x 7
572:2x 2x 11x 13
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 2x 5 = 80
Therefore, the value for common factors is 80.
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 = 35132697600/(2x80)
LCM = 35132697600/160
LCM = 219579360
Thus, we can understand that the LCM of 914,160,420,572 is 219579360.
