Given numbers are 542, 535, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(542, 535) = 289970
GCD(542, 535) = ( 542 x 535 ) / 289970
= 542 / 535
= 542
Step2:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 542, 535, 420 is 1
