Given numbers are 811, 155, 295, 487
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(811, 155) = 125705
GCD(811, 155) = ( 811 x 155 ) / 125705
= 811 / 155
= 811
Step2:
LCM(1, 295) = 295
GCD(1, 295) = ( 1 x 295 ) / 295
= 1 / 295
= 1
Step3:
LCM(1, 487) = 487
GCD(1, 487) = ( 1 x 487 ) / 487
= 1 / 487
= 1
So, Greatest Common Divisor of 811, 155, 295, 487 is 1
