Calculate the LCM of 749,812,669,986,438

Given numbers are 749,812,669,986,438

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 749,812,669,986,438 is 72133616436.

Find LCM of 749,812,669,986,438 with Prime Factorization


2 749, 812, 669, 986, 438
3 749, 406, 669, 493, 219
7 749, 406, 223, 493, 73
29 107, 58, 223, 493, 73
107, 2, 223, 17, 73

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

2 x 3 x 7 x 29 x 107 x 2 x 223 x 17 x 73 = 72133616436

Therefore, the lowest common multiple of 749,812,669,986,438 is 72133616436.

LCM Formula to Find Lowest Common Multiple of 749,812,669,986,438

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.

749 x 812 x 669 x 986 x 438 = 175717489638096

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.

749 : 1, 7, 107, 749

812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812

669 : 1, 3, 223, 669

986 : 1, 2, 17, 29, 34, 58, 493, 986

438 : 1, 2, 3, 6, 73, 146, 219, 438

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,812,669,986,438, is 1.

Now, the common factors can be found like this.

749:7x 107

812:2x 2x 7x 29

669:3x 223

986:2x 17x 29

438:2x 3x 73

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 3x 7x 29 = 2436

Therefore, the value for common factors is 2436.

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 = 175717489638096/(1x2436)

LCM = 175717489638096/2436

LCM = 72133616436

Thus, we can understand that the LCM of 749,812,669,986,438 is 72133616436.
