Given numbers are 785, 531, 235, 870
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(785, 531) = 416835
GCD(785, 531) = ( 785 x 531 ) / 416835
= 785 / 531
= 785
Step2:
LCM(1, 235) = 235
GCD(1, 235) = ( 1 x 235 ) / 235
= 1 / 235
= 1
Step3:
LCM(1, 870) = 870
GCD(1, 870) = ( 1 x 870 ) / 870
= 1 / 870
= 1
So, Greatest Common Divisor of 785, 531, 235, 870 is 1
