Given numbers are 516, 645, 868, 471
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(516, 645) = 2580
GCD(516, 645) = ( 516 x 645 ) / 2580
= 516 / 645
= 516
Step2:
LCM(129, 868) = 111972
GCD(129, 868) = ( 129 x 868 ) / 111972
= 129 / 868
= 129
Step3:
LCM(1, 471) = 471
GCD(1, 471) = ( 1 x 471 ) / 471
= 1 / 471
= 1
So, Greatest Common Divisor of 516, 645, 868, 471 is 1
