Given numbers are 585, 645, 980, 516
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(585, 645) = 25155
GCD(585, 645) = ( 585 x 645 ) / 25155
= 585 / 645
= 585
Step2:
LCM(15, 980) = 2940
GCD(15, 980) = ( 15 x 980 ) / 2940
= 15 / 980
= 15
Step3:
LCM(5, 516) = 2580
GCD(5, 516) = ( 5 x 516 ) / 2580
= 5 / 516
= 5
So, Greatest Common Divisor of 585, 645, 980, 516 is 1
