Given numbers are 645, 285, 304, 662
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 285) = 12255
GCD(645, 285) = ( 645 x 285 ) / 12255
= 645 / 285
= 645
Step2:
LCM(15, 304) = 4560
GCD(15, 304) = ( 15 x 304 ) / 4560
= 15 / 304
= 15
Step3:
LCM(1, 662) = 662
GCD(1, 662) = ( 1 x 662 ) / 662
= 1 / 662
= 1
So, Greatest Common Divisor of 645, 285, 304, 662 is 1
