GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 687) = 192360
GCD(280, 687) = ( 280 x 687 ) / 192360
= 280 / 687
= 280
Step2:
LCM(1, 793) = 793
GCD(1, 793) = ( 1 x 793 ) / 793
= 1 / 793
= 1
Step3:
LCM(1, 964) = 964
GCD(1, 964) = ( 1 x 964 ) / 964
= 1 / 964
= 1
So, Greatest Common Divisor of 280, 687, 793, 964 is 1
