Given numbers are 640, 368, 304, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 368) = 14720
GCD(640, 368) = ( 640 x 368 ) / 14720
= 640 / 368
= 640
Step2:
LCM(16, 304) = 304
GCD(16, 304) = ( 16 x 304 ) / 304
= 16 / 304
= 16
Step3:
LCM(16, 620) = 2480
GCD(16, 620) = ( 16 x 620 ) / 2480
= 16 / 620
= 16
So, Greatest Common Divisor of 640, 368, 304, 620 is 4
