Given numbers are 202,128,570,282
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 202,128,570,282 is 173170560.
Find LCM of 202,128,570,282 with Prime Factorization
| 2 | 202, 128, 570, 282 |
| 3 | 101, 64, 285, 141 |
| 101, 64, 95, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 101 x 64 x 95 x 47 = 173170560
Therefore, the lowest common multiple of 202,128,570,282 is 173170560.
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.
202 x 128 x 570 x 282 = 4156093440
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.
202 : 1, 2, 101, 202
128 : 1, 2, 4, 8, 16, 32, 64, 128
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
282 : 1, 2, 3, 6, 47, 94, 141, 282
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 202,128,570,282, is 2.
Now, the common factors can be found like this.
202:2x 101
128:2x 2x 2x 2x 2x 2x 2
570:2x 3x 5x 19
282:2x 3x 47
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 3 = 12
Therefore, the value for common factors is 12.
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 = 4156093440/(2x12)
LCM = 4156093440/24
LCM = 173170560
Thus, we can understand that the LCM of 202,128,570,282 is 173170560.
