Given numbers are 984,136,749,680
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 984,136,749,680 is 62646360.
Find LCM of 984,136,749,680 with Prime Factorization
| 2 | 984, 136, 749, 680 |
| 2 | 492, 68, 749, 340 |
| 2 | 246, 34, 749, 170 |
| 17 | 123, 17, 749, 85 |
| 123, 1, 749, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 17 x 123 x 1 x 749 x 5 = 62646360
Therefore, the lowest common multiple of 984,136,749,680 is 62646360.
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.
984 x 136 x 749 x 680 = 68159239680
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.
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
136 : 1, 2, 4, 8, 17, 34, 68, 136
749 : 1, 7, 107, 749
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 984,136,749,680, is 1.
Now, the common factors can be found like this.
984:2x 2x 2x 3x 41
136:2x 2x 2x 17
749:7x 107
680:2x 2x 2x 5x 17
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 2x 17 = 1088
Therefore, the value for common factors is 1088.
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 = 68159239680/(1x1088)
LCM = 68159239680/1088
LCM = 62646360
Thus, we can understand that the LCM of 984,136,749,680 is 62646360.
