Given numbers are 291,302,620,744
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 291,302,620,744 is 54486840.
Find LCM of 291,302,620,744 with Prime Factorization
2 | 291, 302, 620, 744 |
2 | 291, 151, 310, 372 |
3 | 291, 151, 155, 186 |
31 | 97, 151, 155, 62 |
97, 151, 5, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 31 x 97 x 151 x 5 x 2 = 54486840
Therefore, the lowest common multiple of 291,302,620,744 is 54486840.
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.
291 x 302 x 620 x 744 = 40538208960
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.
291 : 1, 3, 97, 291
302 : 1, 2, 151, 302
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 291,302,620,744, is 1.
Now, the common factors can be found like this.
291:3x 97
302:2x 151
620:2x 2x 5x 31
744:2x 2x 2x 3x 31
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 31 = 744
Therefore, the value for common factors is 744.
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 = 40538208960/(1x744)
LCM = 40538208960/744
LCM = 54486840
Thus, we can understand that the LCM of 291,302,620,744 is 54486840.
