Given numbers are 985, 805, 68, 858
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(985, 805) = 158585
GCD(985, 805) = ( 985 x 805 ) / 158585
= 985 / 805
= 985
Step2:
LCM(5, 68) = 340
GCD(5, 68) = ( 5 x 68 ) / 340
= 5 / 68
= 5
Step3:
LCM(1, 858) = 858
GCD(1, 858) = ( 1 x 858 ) / 858
= 1 / 858
= 1
So, Greatest Common Divisor of 985, 805, 68, 858 is 1
