The number will 46. (42+4) The number will be 4 greater than their LCM (least common multiple) which is 42. Since the two numbers are relatively prime (have no common prime factors) the LCM is 6 x 7.
1 is the least common factor of the number 2, number 4 and number 7. 28 is the least common multiple of the number 2, number 4 and 7.
The lowest common factor of 6, 4 and 7 is 84.
the LCM (least common multiple) of 4, 6, and 7 is 84.
Write down the factors of each number. Hence 3 = 1,3 4 = 1,2,2,4 5 = 1, 5, 6 = 1,2,3,6 7 = 1, 7 Hence 1, is common to all number. 2, is common to two numbers 3, is common to two numbers 5 is common to one number 7 is common to one number. Hence 1 x 2 x 3 x 5 x 7 = 210 the LCM.
