Given numbers are 905, 648, 397, 127
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(905, 648) = 586440
GCD(905, 648) = ( 905 x 648 ) / 586440
= 905 / 648
= 905
Step2:
LCM(1, 397) = 397
GCD(1, 397) = ( 1 x 397 ) / 397
= 1 / 397
= 1
Step3:
LCM(1, 127) = 127
GCD(1, 127) = ( 1 x 127 ) / 127
= 1 / 127
= 1
So, Greatest Common Divisor of 905, 648, 397, 127 is 1
