Given numbers are 531,495,719,777,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 531,495,719,777,780 is 282806383860.
Find LCM of 531,495,719,777,780 with Prime Factorization
| 3 | 531, 495, 719, 777, 780 |
| 3 | 177, 165, 719, 259, 260 |
| 5 | 59, 55, 719, 259, 260 |
| 59, 11, 719, 259, 52 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 59 x 11 x 719 x 259 x 52 = 282806383860
Therefore, the lowest common multiple of 531,495,719,777,780 is 282806383860.
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.
531 x 495 x 719 x 777 x 780 = 114536585463300
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.
531 : 1, 3, 9, 59, 177, 531
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
719 : 1, 719
777 : 1, 3, 7, 21, 37, 111, 259, 777
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 531,495,719,777,780, is 1.
Now, the common factors can be found like this.
531:3x 3x 59
495:3x 3x 5x 11
719:719
777:3x 7x 37
780:2x 2x 3x 5x 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 3x 3x 3x 5 = 405
Therefore, the value for common factors is 405.
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 = 114536585463300/(1x405)
LCM = 114536585463300/405
LCM = 282806383860
Thus, we can understand that the LCM of 531,495,719,777,780 is 282806383860.
