Given numbers are 780,804,918,602
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 780,804,918,602 is 2406729780.
Find LCM of 780,804,918,602 with Prime Factorization
| 2 | 780, 804, 918, 602 |
| 2 | 390, 402, 459, 301 |
| 3 | 195, 201, 459, 301 |
| 65, 67, 153, 301 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 65 x 67 x 153 x 301 = 2406729780
Therefore, the lowest common multiple of 780,804,918,602 is 2406729780.
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.
780 x 804 x 918 x 602 = 346569088320
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.
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
602 : 1, 2, 7, 14, 43, 86, 301, 602
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,804,918,602, is 2.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
804:2x 2x 3x 67
918:2x 3x 3x 3x 17
602:2x 7x 43
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 3 = 72
Therefore, the value for common factors is 72.
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 = 346569088320/(2x72)
LCM = 346569088320/144
LCM = 2406729780
Thus, we can understand that the LCM of 780,804,918,602 is 2406729780.
