Given numbers are 355, 497, 390, 340
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(355, 497) = 2485
GCD(355, 497) = ( 355 x 497 ) / 2485
= 355 / 497
= 355
Step2:
LCM(71, 390) = 27690
GCD(71, 390) = ( 71 x 390 ) / 27690
= 71 / 390
= 71
Step3:
LCM(1, 340) = 340
GCD(1, 340) = ( 1 x 340 ) / 340
= 1 / 340
= 1
So, Greatest Common Divisor of 355, 497, 390, 340 is 1
