Given numbers are 452, 780, 665, 908
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(452, 780) = 88140
GCD(452, 780) = ( 452 x 780 ) / 88140
= 452 / 780
= 452
Step2:
LCM(4, 665) = 2660
GCD(4, 665) = ( 4 x 665 ) / 2660
= 4 / 665
= 4
Step3:
LCM(1, 908) = 908
GCD(1, 908) = ( 1 x 908 ) / 908
= 1 / 908
= 1
So, Greatest Common Divisor of 452, 780, 665, 908 is 1
