Find LCM of 603,630,872,690 with Prime Factorization


2 603, 630, 872, 690
3 603, 315, 436, 345
3 201, 105, 436, 115
5 67, 35, 436, 115
67, 7, 436, 23

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

2 x 3 x 3 x 5 x 67 x 7 x 436 x 23 = 423281880

Therefore, the lowest common multiple of 603,630,872,690 is 423281880.

LCM Formula to Find Lowest Common Multiple of 603,630,872,690

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.

603 x 630 x 872 x 690 = 228572215200

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.

603 : 1, 3, 9, 67, 201, 603

630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630

872 : 1, 2, 4, 8, 109, 218, 436, 872

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 603,630,872,690, is 1.

Now, the common factors can be found like this.

603:3x 3x 67

630:2x 3x 3x 5x 7

872:2x 2x 2x 109

690:2x 3x 5x 23

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 3x 3x 5 = 540

Therefore, the value for common factors is 540.

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 = 228572215200/(1x540)

LCM = 228572215200/540

LCM = 423281880

Thus, we can understand that the LCM of 603,630,872,690 is 423281880.
