GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 392) = 335160
GCD(855, 392) = ( 855 x 392 ) / 335160
= 855 / 392
= 855
Step2:
LCM(1, 637) = 637
GCD(1, 637) = ( 1 x 637 ) / 637
= 1 / 637
= 1
Step3:
LCM(1, 127) = 127
GCD(1, 127) = ( 1 x 127 ) / 127
= 1 / 127
= 1
So, Greatest Common Divisor of 855, 392, 637, 127 is 1
