Given numbers are 511, 217, 447, 140
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(511, 217) = 15841
GCD(511, 217) = ( 511 x 217 ) / 15841
= 511 / 217
= 511
Step2:
LCM(7, 447) = 3129
GCD(7, 447) = ( 7 x 447 ) / 3129
= 7 / 447
= 7
Step3:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
So, Greatest Common Divisor of 511, 217, 447, 140 is 1
