Given numbers are 309, 612, 860, 892
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(309, 612) = 63036
GCD(309, 612) = ( 309 x 612 ) / 63036
= 309 / 612
= 309
Step2:
LCM(3, 860) = 2580
GCD(3, 860) = ( 3 x 860 ) / 2580
= 3 / 860
= 3
Step3:
LCM(1, 892) = 892
GCD(1, 892) = ( 1 x 892 ) / 892
= 1 / 892
= 1
So, Greatest Common Divisor of 309, 612, 860, 892 is 1
