Given numbers are 186, 453, 686, 428
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(186, 453) = 28086
GCD(186, 453) = ( 186 x 453 ) / 28086
= 186 / 453
= 186
Step2:
LCM(3, 686) = 2058
GCD(3, 686) = ( 3 x 686 ) / 2058
= 3 / 686
= 3
Step3:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
So, Greatest Common Divisor of 186, 453, 686, 428 is 1
