Given numbers are 973,446,782,302,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 973,446,782,302,721 is 2638995370634.
Find LCM of 973,446,782,302,721 with Prime Factorization
| 2 | 973, 446, 782, 302, 721 |
| 7 | 973, 223, 391, 151, 721 |
| 139, 223, 391, 151, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 139 x 223 x 391 x 151 x 103 = 2638995370634
Therefore, the lowest common multiple of 973,446,782,302,721 is 2638995370634.
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.
973 x 446 x 782 x 302 x 721 = 73891870377752
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.
973 : 1, 7, 139, 973
446 : 1, 2, 223, 446
782 : 1, 2, 17, 23, 34, 46, 391, 782
302 : 1, 2, 151, 302
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 973,446,782,302,721, is 1.
Now, the common factors can be found like this.
973:7x 139
446:2x 223
782:2x 17x 23
302:2x 151
721:7x 103
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 7 = 28
Therefore, the value for common factors is 28.
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 = 73891870377752/(1x28)
LCM = 73891870377752/28
LCM = 2638995370634
Thus, we can understand that the LCM of 973,446,782,302,721 is 2638995370634.
