Given numbers are 127, 821, 135, 142
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(127, 821) = 104267
GCD(127, 821) = ( 127 x 821 ) / 104267
= 127 / 821
= 127
Step2:
LCM(1, 135) = 135
GCD(1, 135) = ( 1 x 135 ) / 135
= 1 / 135
= 1
Step3:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
So, Greatest Common Divisor of 127, 821, 135, 142 is 1
