Given numbers are 257,570,658,938,372
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 257,570,658,938,372 is 200202902340.
Find LCM of 257,570,658,938,372 with Prime Factorization
| 2 | 257, 570, 658, 938, 372 |
| 3 | 257, 285, 329, 469, 186 |
| 7 | 257, 95, 329, 469, 62 |
| 257, 95, 47, 67, 62 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 257 x 95 x 47 x 67 x 62 = 200202902340
Therefore, the lowest common multiple of 257,570,658,938,372 is 200202902340.
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.
257 x 570 x 658 x 938 x 372 = 33634087593120
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.
257 : 1, 257
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
658 : 1, 2, 7, 14, 47, 94, 329, 658
938 : 1, 2, 7, 14, 67, 134, 469, 938
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 257,570,658,938,372, is 1.
Now, the common factors can be found like this.
257:257
570:2x 3x 5x 19
658:2x 7x 47
938:2x 7x 67
372:2x 2x 3x 31
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 7 = 168
Therefore, the value for common factors is 168.
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 = 33634087593120/(1x168)
LCM = 33634087593120/168
LCM = 200202902340
Thus, we can understand that the LCM of 257,570,658,938,372 is 200202902340.
