Given numbers are 760,870,618,380
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 760,870,618,380 is 6810360.
Find LCM of 760,870,618,380 with Prime Factorization
| 2 | 760, 870, 618, 380 |
| 2 | 380, 435, 309, 190 |
| 3 | 95, 435, 309, 190 |
| 5 | 95, 145, 103, 190 |
| 19 | 19, 29, 103, 38 |
| 1, 29, 103, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 19 x 1 x 29 x 103 x 2 = 6810360
Therefore, the lowest common multiple of 760,870,618,380 is 6810360.
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.
760 x 870 x 618 x 380 = 155276208000
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.
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
618 : 1, 2, 3, 6, 103, 206, 309, 618
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 760,870,618,380, is 2.
Now, the common factors can be found like this.
760:2x 2x 2x 5x 19
870:2x 3x 5x 29
618:2x 3x 103
380:2x 2x 5x 19
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 5x 5x 19 = 11400
Therefore, the value for common factors is 11400.
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 = 155276208000/(2x11400)
LCM = 155276208000/22800
LCM = 6810360
Thus, we can understand that the LCM of 760,870,618,380 is 6810360.
