Find LCM of 151,378,972,421 with Prime Factorization
2 | 151, 378, 972, 421 |
3 | 151, 189, 486, 421 |
3 | 151, 63, 162, 421 |
3 | 151, 21, 54, 421 |
151, 7, 18, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 151 x 7 x 18 x 421 = 432537084
Therefore, the lowest common multiple of 151,378,972,421 is 432537084.
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.
151 x 378 x 972 x 421 = 23357002536
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.
151 : 1, 151
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 151,378,972,421, is 1.
Now, the common factors can be found like this.
151:151
378:2x 3x 3x 3x 7
972:2x 2x 3x 3x 3x 3x 3
421:421
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 23357002536/(1x54)
LCM = 23357002536/54
LCM = 432537084
Thus, we can understand that the LCM of 151,378,972,421 is 432537084.
