Find LCM of 476,783,972,321 with Prime Factorization
2 | 476, 783, 972, 321 |
2 | 238, 783, 486, 321 |
3 | 119, 783, 243, 321 |
3 | 119, 261, 81, 107 |
3 | 119, 87, 27, 107 |
119, 29, 9, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 119 x 29 x 9 x 107 = 358917804
Therefore, the lowest common multiple of 476,783,972,321 is 358917804.
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.
476 x 783 x 972 x 321 = 116289368496
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.
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
783 : 1, 3, 9, 27, 29, 87, 261, 783
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,783,972,321, is 1.
Now, the common factors can be found like this.
476:2x 2x 7x 17
783:3x 3x 3x 29
972:2x 2x 3x 3x 3x 3x 3
321:3x 107
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 3x 3x 3x 3 = 324
Therefore, the value for common factors is 324.
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 = 116289368496/(1x324)
LCM = 116289368496/324
LCM = 358917804
Thus, we can understand that the LCM of 476,783,972,321 is 358917804.
