Given numbers are 857, 745, 945, 511
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(857, 745) = 638465
GCD(857, 745) = ( 857 x 745 ) / 638465
= 857 / 745
= 857
Step2:
LCM(1, 945) = 945
GCD(1, 945) = ( 1 x 945 ) / 945
= 1 / 945
= 1
Step3:
LCM(1, 511) = 511
GCD(1, 511) = ( 1 x 511 ) / 511
= 1 / 511
= 1
So, Greatest Common Divisor of 857, 745, 945, 511 is 1
