Given numbers are 686, 904, 356, 543
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(686, 904) = 310072
GCD(686, 904) = ( 686 x 904 ) / 310072
= 686 / 904
= 686
Step2:
LCM(2, 356) = 356
GCD(2, 356) = ( 2 x 356 ) / 356
= 2 / 356
= 2
Step3:
LCM(2, 543) = 1086
GCD(2, 543) = ( 2 x 543 ) / 1086
= 2 / 543
= 2
So, Greatest Common Divisor of 686, 904, 356, 543 is 1
