GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 228) = 3420
GCD(855, 228) = ( 855 x 228 ) / 3420
= 855 / 228
= 855
Step2:
LCM(57, 548) = 31236
GCD(57, 548) = ( 57 x 548 ) / 31236
= 57 / 548
= 57
Step3:
LCM(1, 398) = 398
GCD(1, 398) = ( 1 x 398 ) / 398
= 1 / 398
= 1
So, Greatest Common Divisor of 855, 228, 548, 398 is 1
