Given numbers are 861, 516, 405, 368
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 516) = 148092
GCD(861, 516) = ( 861 x 516 ) / 148092
= 861 / 516
= 861
Step2:
LCM(3, 405) = 405
GCD(3, 405) = ( 3 x 405 ) / 405
= 3 / 405
= 3
Step3:
LCM(3, 368) = 1104
GCD(3, 368) = ( 3 x 368 ) / 1104
= 3 / 368
= 3
So, Greatest Common Divisor of 861, 516, 405, 368 is 1
