Given numbers are 315, 940, 815, 641
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(315, 940) = 59220
GCD(315, 940) = ( 315 x 940 ) / 59220
= 315 / 940
= 315
Step2:
LCM(5, 815) = 815
GCD(5, 815) = ( 5 x 815 ) / 815
= 5 / 815
= 5
Step3:
LCM(5, 641) = 3205
GCD(5, 641) = ( 5 x 641 ) / 3205
= 5 / 641
= 5
So, Greatest Common Divisor of 315, 940, 815, 641 is 1
