Given numbers are 861, 612, 985, 457
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(861, 612) = 175644
GCD(861, 612) = ( 861 x 612 ) / 175644
= 861 / 612
= 861
Step2:
LCM(3, 985) = 2955
GCD(3, 985) = ( 3 x 985 ) / 2955
= 3 / 985
= 3
Step3:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
So, Greatest Common Divisor of 861, 612, 985, 457 is 1
