Given numbers are 445, 780, 815, 469
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(445, 780) = 69420
GCD(445, 780) = ( 445 x 780 ) / 69420
= 445 / 780
= 445
Step2:
LCM(5, 815) = 815
GCD(5, 815) = ( 5 x 815 ) / 815
= 5 / 815
= 5
Step3:
LCM(5, 469) = 2345
GCD(5, 469) = ( 5 x 469 ) / 2345
= 5 / 469
= 5
So, Greatest Common Divisor of 445, 780, 815, 469 is 1
