Given numbers are 782, 410, 290, 305
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 410) = 160310
GCD(782, 410) = ( 782 x 410 ) / 160310
= 782 / 410
= 782
Step2:
LCM(2, 290) = 290
GCD(2, 290) = ( 2 x 290 ) / 290
= 2 / 290
= 2
Step3:
LCM(2, 305) = 610
GCD(2, 305) = ( 2 x 305 ) / 610
= 2 / 305
= 2
So, Greatest Common Divisor of 782, 410, 290, 305 is 1
