Given numbers are 736,550,540,842,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 736,550,540,842,420 is 16104765600.
Find LCM of 736,550,540,842,420 with Prime Factorization
| 2 | 736, 550, 540, 842, 420 |
| 2 | 368, 275, 270, 421, 210 |
| 3 | 184, 275, 135, 421, 105 |
| 5 | 184, 275, 45, 421, 35 |
| 184, 55, 9, 421, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 184 x 55 x 9 x 421 x 7 = 16104765600
Therefore, the lowest common multiple of 736,550,540,842,420 is 16104765600.
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.
736 x 550 x 540 x 842 x 420 = 77302874880000
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.
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
842 : 1, 2, 421, 842
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 736,550,540,842,420, is 2.
Now, the common factors can be found like this.
736:2x 2x 2x 2x 2x 23
550:2x 5x 5x 11
540:2x 2x 3x 3x 3x 5
842:2x 421
420:2x 2x 3x 5x 7
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 2x 3x 5x 5 = 2400
Therefore, the value for common factors is 2400.
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 = 77302874880000/(2x2400)
LCM = 77302874880000/4800
LCM = 16104765600
Thus, we can understand that the LCM of 736,550,540,842,420 is 16104765600.
