Given numbers are 757,370,980,356,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 757,370,980,356,390 is 95274854220.
Find LCM of 757,370,980,356,390 with Prime Factorization
| 2 | 757, 370, 980, 356, 390 |
| 2 | 757, 185, 490, 178, 195 |
| 5 | 757, 185, 245, 89, 195 |
| 757, 37, 49, 89, 39 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 757 x 37 x 49 x 89 x 39 = 95274854220
Therefore, the lowest common multiple of 757,370,980,356,390 is 95274854220.
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.
757 x 370 x 980 x 356 x 390 = 38109941688000
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.
757 : 1, 757
370 : 1, 2, 5, 10, 37, 74, 185, 370
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
356 : 1, 2, 4, 89, 178, 356
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 757,370,980,356,390, is 1.
Now, the common factors can be found like this.
757:757
370:2x 5x 37
980:2x 2x 5x 7x 7
356:2x 2x 89
390:2x 3x 5x 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 5x 5 = 400
Therefore, the value for common factors is 400.
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 = 38109941688000/(1x400)
LCM = 38109941688000/400
LCM = 95274854220
Thus, we can understand that the LCM of 757,370,980,356,390 is 95274854220.
