Given numbers are 127, 131, 369, 561
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(127, 131) = 16637
GCD(127, 131) = ( 127 x 131 ) / 16637
= 127 / 131
= 127
Step2:
LCM(1, 369) = 369
GCD(1, 369) = ( 1 x 369 ) / 369
= 1 / 369
= 1
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 127, 131, 369, 561 is 1
