The LCM of 561,365,666,370 is 45457830.
Find LCM of 561,365,666,370 with Prime Factorization
| 2 | 561, 365, 666, 370 |
| 3 | 561, 365, 333, 185 |
| 5 | 187, 365, 111, 185 |
| 37 | 187, 73, 111, 37 |
| 187, 73, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 37 x 187 x 73 x 3 x 1 = 45457830
Therefore, the lowest common multiple of 561,365,666,370 is 45457830.
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.
561 x 365 x 666 x 370 = 50458191300
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
365 : 1, 5, 73, 365
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
370 : 1, 2, 5, 10, 37, 74, 185, 370
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,365,666,370, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
365:5x 73
666:2x 3x 3x 37
370:2x 5x 37
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 5x 37 = 1110
Therefore, the value for common factors is 1110.
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 = 50458191300/(1x1110)
LCM = 50458191300/1110
LCM = 45457830
Thus, we can understand that the LCM of 561,365,666,370 is 45457830.
