Given numbers are 55, 28, 24, 42
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(55, 28) = 1540
GCD(55, 28) = ( 55 x 28 ) / 1540
= 55 / 28
= 55
Step2:
LCM(1, 24) = 24
GCD(1, 24) = ( 1 x 24 ) / 24
= 1 / 24
= 1
Step3:
LCM(1, 42) = 42
GCD(1, 42) = ( 1 x 42 ) / 42
= 1 / 42
= 1
So, Greatest Common Divisor of 55, 28, 24, 42 is 1
