Consecutive 23251

Find the LCM of four consecutive natural numbers. Its sum is 42.

Correct answer:

x =  1980

Step-by-step explanation:

a+(a+1)+(a+2)+(a+3)=42  4a=36  a=436=9  a=9  b=a+1=9+1=10 c=b+1=10+1=11 d=c+1=11+1=12  9=32 10=25 11 ...  prime number 12=223 LCM(9,10,11,12)=2232511=1980  x=LCM(a,b,c,d)=LCM(9,10,11,12)=1980
