Given numbers are 973, 990, 419, 687
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(973, 990) = 963270
GCD(973, 990) = ( 973 x 990 ) / 963270
= 973 / 990
= 973
Step2:
LCM(1, 419) = 419
GCD(1, 419) = ( 1 x 419 ) / 419
= 1 / 419
= 1
Step3:
LCM(1, 687) = 687
GCD(1, 687) = ( 1 x 687 ) / 687
= 1 / 687
= 1
So, Greatest Common Divisor of 973, 990, 419, 687 is 1
