Find LCM of 972,438,321,268,319 with Prime Factorization
2 | 972, 438, 321, 268, 319 |
2 | 486, 219, 321, 134, 319 |
3 | 243, 219, 321, 67, 319 |
81, 73, 107, 67, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 81 x 73 x 107 x 67 x 319 = 162270056916
Therefore, the lowest common multiple of 972,438,321,268,319 is 162270056916.
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.
972 x 438 x 321 x 268 x 319 = 11683444097952
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
438 : 1, 2, 3, 6, 73, 146, 219, 438
321 : 1, 3, 107, 321
268 : 1, 2, 4, 67, 134, 268
319 : 1, 11, 29, 319
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,438,321,268,319, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
438:2x 3x 73
321:3x 107
268:2x 2x 67
319:11x 29
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 11683444097952/(1x72)
LCM = 11683444097952/72
LCM = 162270056916
Thus, we can understand that the LCM of 972,438,321,268,319 is 162270056916.
