Can someone help me on 1 and B please

A: gcf=7 lcm=42

B: gcf= 5, lcm=75

Step-by-step explanation:

1a) GCF= 7

     LCM= 42

b) GCF= 5

     LCM= 150

Step-by-step explanation: THE QUESTION IS LOOKING FOR THE LOWEST COMMON MULTIPLE OF BOTH NUMBERS GIVEN . MEANING THE SMALLEST MULTIPLE NUMBER THAT IS MADE BY BOTH NUMBERS.FOR EXAMPLE; LOOKING AT THE MULTIPLE  NUMBERS OF 14 AND 21, 42 IS THEIR LOWEST COMMON MULTIPLE BECAUSE ITS THE FIRST NUMBER THEY BOTH HAVE AMONGST THEM.

THE GREATEST COMMON FACTOR IS THE LARGEST NUMBER THAT ENTERS INTO BOTH THE NUMBERS GIVEN WITHOUT LEVING A REMAINDER.

so, 4/9 of the way from -8 to 10 is 0!

seems like d
