The LCM of 38 and 42 is: 798
The GCF and LCM of 24 and 42 are 6 and 168 respectively.
The GCF is 6. That makes the LCM 42.
The LCM is: 1302The GCF is: 2
Lcm: 126 gcf: 7
GCF is 2.LCM is 42.The GCF is 2.
Whenever one number is a multiple of the other, the LCM is the larger number and the GCF is the smaller number. The difference is 42.
The factors of 42 are 1, 2, 3, 6, 7, 14, 21 and 42. The factors of 38 are 1, 2, 19 and 38. 2 is the greatest factor which divides both 38 and 42. So, the GCF of 42 and 38 is 2.
The LCM of 6 and 21 is 42. Their GCF is 3.
GCF is 7. LCM is 420
GCF: 7 LCM: 210
Because 210 is the smallest number that both 30 and 42 divide into equally with no remainder.
