Answer:
Explanation:
To begin with, find the greatest common divisor. Divide by 10 because they both end in a zero. 1050/10 equals 105 and 2520/10 equals 252. Now find the largest number that can be divided from both of them to get a whole number. Try the first 10 numbers, and you'll find that 3 divides from both. 105/3=35 and 252/3=84. Finally, you'll see that 7 divides from both, and you get 35/7=5 and 84/7=12. Now take all the numbers you divided by and multiply them. 3 x 7 x 10 = 210. This is the greatest common divisor. Now we use the lcm formula, |a*b| / GCD. | | means absolute value, which removes the negative, if there is any. Using this, we do (1050*2520)/210 and we get 12600. Hope this helps!
