Given numbers are 780, 432, 576, 208
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 432) = 28080
GCD(780, 432) = ( 780 x 432 ) / 28080
= 780 / 432
= 780
Step2:
LCM(12, 576) = 576
GCD(12, 576) = ( 12 x 576 ) / 576
= 12 / 576
= 12
Step3:
LCM(12, 208) = 624
GCD(12, 208) = ( 12 x 208 ) / 624
= 12 / 208
= 12
So, Greatest Common Divisor of 780, 432, 576, 208 is 4
