Given numbers are 661, 905, 516, 127
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(661, 905) = 598205
GCD(661, 905) = ( 661 x 905 ) / 598205
= 661 / 905
= 661
Step2:
LCM(1, 516) = 516
GCD(1, 516) = ( 1 x 516 ) / 516
= 1 / 516
= 1
Step3:
LCM(1, 127) = 127
GCD(1, 127) = ( 1 x 127 ) / 127
= 1 / 127
= 1
So, Greatest Common Divisor of 661, 905, 516, 127 is 1
