Given numbers are 680, 870, 809, 792
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 870) = 59160
GCD(680, 870) = ( 680 x 870 ) / 59160
= 680 / 870
= 680
Step2:
LCM(10, 809) = 8090
GCD(10, 809) = ( 10 x 809 ) / 8090
= 10 / 809
= 10
Step3:
LCM(1, 792) = 792
GCD(1, 792) = ( 1 x 792 ) / 792
= 1 / 792
= 1
So, Greatest Common Divisor of 680, 870, 809, 792 is 1
