Given numbers are 138, 980, 801, 127
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(138, 980) = 67620
GCD(138, 980) = ( 138 x 980 ) / 67620
= 138 / 980
= 138
Step2:
LCM(2, 801) = 1602
GCD(2, 801) = ( 2 x 801 ) / 1602
= 2 / 801
= 2
Step3:
LCM(1, 127) = 127
GCD(1, 127) = ( 1 x 127 ) / 127
= 1 / 127
= 1
So, Greatest Common Divisor of 138, 980, 801, 127 is 1
