GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 864) = 337824
GCD(391, 864) = ( 391 x 864 ) / 337824
= 391 / 864
= 391
Step2:
LCM(1, 541) = 541
GCD(1, 541) = ( 1 x 541 ) / 541
= 1 / 541
= 1
Step3:
LCM(1, 156) = 156
GCD(1, 156) = ( 1 x 156 ) / 156
= 1 / 156
= 1
So, Greatest Common Divisor of 391, 864, 541, 156 is 1
