The LCM of 741,741,430,646 is 5416710.

Find LCM of 741,741,430,646 with Prime Factorization


2 741, 741, 430, 646
3 741, 741, 215, 323
13 247, 247, 215, 323
19 19, 19, 215, 323
1, 1, 215, 17

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 13 x 19 x 1 x 1 x 215 x 17 = 5416710

Therefore, the lowest common multiple of 741,741,430,646 is 5416710.

LCM Formula to Find Lowest Common Multiple of 741,741,430,646

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.

741 x 741 x 430 x 646 = 152523720180

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.

741 : 1, 3, 13, 19, 39, 57, 247, 741

741 : 1, 3, 13, 19, 39, 57, 247, 741

430 : 1, 2, 5, 10, 43, 86, 215, 430

646 : 1, 2, 17, 19, 34, 38, 323, 646

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 741,741,430,646, is 1.

Now, the common factors can be found like this.

741:3x 13x 19

741:3x 13x 19

430:2x 5x 43

646:2x 17x 19

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 13x 19x 19 = 28158

Therefore, the value for common factors is 28158.

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 = 152523720180/(1x28158)

LCM = 152523720180/28158

LCM = 5416710

Thus, we can understand that the LCM of 741,741,430,646 is 5416710.
