GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(785, 828) = 649980
GCD(785, 828) = ( 785 x 828 ) / 649980
= 785 / 828
= 785
Step2:
LCM(1, 725) = 725
GCD(1, 725) = ( 1 x 725 ) / 725
= 1 / 725
= 1
Step3:
LCM(1, 520) = 520
GCD(1, 520) = ( 1 x 520 ) / 520
= 1 / 520
= 1
So, Greatest Common Divisor of 785, 828, 725, 520 is 1
