<span>To solve these GCF and LCM problems, factor the numbers you're working with into primes:
3780 = 2*2*3*3*3*5*7
180 = 2*2*3*3*5
</span><span>We know that the LCM of the two numbers, call them A and B, = 3780 and that A = 180. The greatest common factor of 180 and B = 18 so B has factors 2*3*3 in common with 180 but no other factors in common with 180. So, B has no more 2's and no 5's
</span><span>Now, LCM(180,B) = 3780. So, A or B must have each of the factors of 3780. B needs another factor of 3 and a factor of 7 since LCM(A,B) needs for either A or B to have a factor of 2*2, which A has, and a factor of 3*3*3, which B will have with another factor of 3, and a factor of 7, which B will have.
So, B = 2*3*3*3*7 = 378.</span>

Answer:
y=620 lemme know if this helped by pressing thanks :)
Step-by-step explanation:
Answer:
The area is 21 inches
Step-by-step explanation:
3x3=9
3x2=6
9+6=15 ( inches in the white box )
6x6=36 ( area of the whole box)
36-15= 21 ( inches in the shaded area )
The answer is Choice C: 51
