Given numbers are 408, 164, 214, 787
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 164) = 16728
GCD(408, 164) = ( 408 x 164 ) / 16728
= 408 / 164
= 408
Step2:
LCM(4, 214) = 428
GCD(4, 214) = ( 4 x 214 ) / 428
= 4 / 214
= 4
Step3:
LCM(2, 787) = 1574
GCD(2, 787) = ( 2 x 787 ) / 1574
= 2 / 787
= 2
So, Greatest Common Divisor of 408, 164, 214, 787 is 1
