Given numbers are 504, 392, 162, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(504, 392) = 3528
GCD(504, 392) = ( 504 x 392 ) / 3528
= 504 / 392
= 504
Step2:
LCM(56, 162) = 4536
GCD(56, 162) = ( 56 x 162 ) / 4536
= 56 / 162
= 56
Step3:
LCM(2, 420) = 420
GCD(2, 420) = ( 2 x 420 ) / 420
= 2 / 420
= 2
So, Greatest Common Divisor of 504, 392, 162, 420 is 2
