GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 810) = 51840
GCD(640, 810) = ( 640 x 810 ) / 51840
= 640 / 810
= 640
Step2:
LCM(10, 982) = 4910
GCD(10, 982) = ( 10 x 982 ) / 4910
= 10 / 982
= 10
Step3:
LCM(2, 368) = 368
GCD(2, 368) = ( 2 x 368 ) / 368
= 2 / 368
= 2
So, Greatest Common Divisor of 640, 810, 982, 368 is 2
