Given numbers are 452, 818, 780, 395
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(452, 818) = 184868
GCD(452, 818) = ( 452 x 818 ) / 184868
= 452 / 818
= 452
Step2:
LCM(2, 780) = 780
GCD(2, 780) = ( 2 x 780 ) / 780
= 2 / 780
= 2
Step3:
LCM(2, 395) = 790
GCD(2, 395) = ( 2 x 395 ) / 790
= 2 / 395
= 2
So, Greatest Common Divisor of 452, 818, 780, 395 is 1
