Given numbers are 785, 646, 828, 240
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(785, 646) = 507110
GCD(785, 646) = ( 785 x 646 ) / 507110
= 785 / 646
= 785
Step2:
LCM(1, 828) = 828
GCD(1, 828) = ( 1 x 828 ) / 828
= 1 / 828
= 1
Step3:
LCM(1, 240) = 240
GCD(1, 240) = ( 1 x 240 ) / 240
= 1 / 240
= 1
So, Greatest Common Divisor of 785, 646, 828, 240 is 1
