GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 298) = 58110
GCD(390, 298) = ( 390 x 298 ) / 58110
= 390 / 298
= 390
Step2:
LCM(2, 368) = 368
GCD(2, 368) = ( 2 x 368 ) / 368
= 2 / 368
= 2
Step3:
LCM(2, 570) = 570
GCD(2, 570) = ( 2 x 570 ) / 570
= 2 / 570
= 2
So, Greatest Common Divisor of 390, 298, 368, 570 is 2
