GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 548) = 350172
GCD(639, 548) = ( 639 x 548 ) / 350172
= 639 / 548
= 639
Step2:
LCM(1, 392) = 392
GCD(1, 392) = ( 1 x 392 ) / 392
= 1 / 392
= 1
Step3:
LCM(1, 192) = 192
GCD(1, 192) = ( 1 x 192 ) / 192
= 1 / 192
= 1
So, Greatest Common Divisor of 639, 548, 392, 192 is 1
