Given numbers are 769,749,660,781,273
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 769,749,660,781,273 is 350876105580.
Find LCM of 769,749,660,781,273 with Prime Factorization
| 3 | 769, 749, 660, 781, 273 |
| 7 | 769, 749, 220, 781, 91 |
| 11 | 769, 107, 220, 781, 13 |
| 769, 107, 20, 71, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 769 x 107 x 20 x 71 x 13 = 350876105580
Therefore, the lowest common multiple of 769,749,660,781,273 is 350876105580.
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.
769 x 749 x 660 x 781 x 273 = 81052380388980
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.
769 : 1, 769
749 : 1, 7, 107, 749
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
781 : 1, 11, 71, 781
273 : 1, 3, 7, 13, 21, 39, 91, 273
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,749,660,781,273, is 1.
Now, the common factors can be found like this.
769:769
749:7x 107
660:2x 2x 3x 5x 11
781:11x 71
273:3x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 11 = 231
Therefore, the value for common factors is 231.
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 = 81052380388980/(1x231)
LCM = 81052380388980/231
LCM = 350876105580
Thus, we can understand that the LCM of 769,749,660,781,273 is 350876105580.
