GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 825) = 25575
GCD(155, 825) = ( 155 x 825 ) / 25575
= 155 / 825
= 155
Step2:
LCM(5, 212) = 1060
GCD(5, 212) = ( 5 x 212 ) / 1060
= 5 / 212
= 5
Step3:
LCM(1, 279) = 279
GCD(1, 279) = ( 1 x 279 ) / 279
= 1 / 279
= 1
So, Greatest Common Divisor of 155, 825, 212, 279 is 1
