GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(140, 428) = 14980
GCD(140, 428) = ( 140 x 428 ) / 14980
= 140 / 428
= 140
Step2:
LCM(4, 380) = 380
GCD(4, 380) = ( 4 x 380 ) / 380
= 4 / 380
= 4
Step3:
LCM(4, 790) = 1580
GCD(4, 790) = ( 4 x 790 ) / 1580
= 4 / 790
= 4
So, Greatest Common Divisor of 140, 428, 380, 790 is 2
