GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 642) = 89880
GCD(280, 642) = ( 280 x 642 ) / 89880
= 280 / 642
= 280
Step2:
LCM(2, 312) = 312
GCD(2, 312) = ( 2 x 312 ) / 312
= 2 / 312
= 2
Step3:
LCM(2, 346) = 346
GCD(2, 346) = ( 2 x 346 ) / 346
= 2 / 346
= 2
So, Greatest Common Divisor of 280, 642, 312, 346 is 2
