Given numbers are 300, 978, 175, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(300, 978) = 48900
GCD(300, 978) = ( 300 x 978 ) / 48900
= 300 / 978
= 300
Step2:
LCM(6, 175) = 1050
GCD(6, 175) = ( 6 x 175 ) / 1050
= 6 / 175
= 6
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 300, 978, 175, 645 is 1
