GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(124, 340) = 10540
GCD(124, 340) = ( 124 x 340 ) / 10540
= 124 / 340
= 124
Step2:
LCM(4, 580) = 580
GCD(4, 580) = ( 4 x 580 ) / 580
= 4 / 580
= 4
Step3:
LCM(4, 308) = 308
GCD(4, 308) = ( 4 x 308 ) / 308
= 4 / 308
= 4
So, Greatest Common Divisor of 124, 340, 580, 308 is 4
