GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(578, 306) = 5202
GCD(578, 306) = ( 578 x 306 ) / 5202
= 578 / 306
= 578
Step2:
LCM(34, 388) = 6596
GCD(34, 388) = ( 34 x 388 ) / 6596
= 34 / 388
= 34
Step3:
LCM(2, 490) = 490
GCD(2, 490) = ( 2 x 490 ) / 490
= 2 / 490
= 2
So, Greatest Common Divisor of 578, 306, 388, 490 is 2
