GCF: 7
LCM: 210
LCM(42, 70, 105) = 210
If that's really 4270 and 84, the GCF is 14 and the LCM is 25620. If that's 42, 70 and 84, the GCF is 14 and the LCM is 420.
For 105, 84, 70, 49 the LCM is: 2,940
The LCM is: 210210
LCM = 70 GCF = 7
The LCM is 210.
LCM(42, 70, 105) = 210
If that's really 4270 and 84, the GCF is 14 and the LCM is 25620. If that's 42, 70 and 84, the GCF is 14 and the LCM is 420.
The GCF is 7.
To find the greatest common factor (GCF) of 42, 70, and 105, we first need to find the prime factorization of each number. 42 = 2 x 3 x 7 70 = 2 x 5 x 7 105 = 3 x 5 x 7 The GCF is the product of the common prime factors raised to the lowest power they appear in all three numbers. Therefore, the GCF of 42, 70, and 105 is 7.
The GCF is 5.
LCM(30, 70, 105) = 210
For 105, 84, 70, 49 the LCM is: 2,940
840 and 70, respectively.
The LCM is: 210210
LCM of 42 70 and 98 is 1470.
