Given numbers are 194, 128, 555, 681
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(194, 128) = 12416
GCD(194, 128) = ( 194 x 128 ) / 12416
= 194 / 128
= 194
Step2:
LCM(2, 555) = 1110
GCD(2, 555) = ( 2 x 555 ) / 1110
= 2 / 555
= 2
Step3:
LCM(1, 681) = 681
GCD(1, 681) = ( 1 x 681 ) / 681
= 1 / 681
= 1
So, Greatest Common Divisor of 194, 128, 555, 681 is 1
