Find LCM of 637,972,344,343 with Prime Factorization


2 637, 972, 344, 343
2 637, 486, 172, 343
7 637, 243, 86, 343
7 91, 243, 86, 49
13, 243, 86, 7

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

2 x 2 x 7 x 7 x 13 x 243 x 86 x 7 = 372736728

Therefore, the lowest common multiple of 637,972,344,343 is 372736728.

LCM Formula to Find Lowest Common Multiple of 637,972,344,343

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.

637 x 972 x 344 x 343 = 73056398688

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.

637 : 1, 7, 13, 49, 91, 637

972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972

344 : 1, 2, 4, 8, 43, 86, 172, 344

343 : 1, 7, 49, 343

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,972,344,343, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

972:2x 2x 3x 3x 3x 3x 3

344:2x 2x 2x 43

343:7x 7x 7

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 7x 7 = 196

Therefore, the value for common factors is 196.

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 = 73056398688/(1x196)

LCM = 73056398688/196

LCM = 372736728

Thus, we can understand that the LCM of 637,972,344,343 is 372736728.
