GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 826) = 280840
GCD(680, 826) = ( 680 x 826 ) / 280840
= 680 / 826
= 680
Step2:
LCM(2, 640) = 640
GCD(2, 640) = ( 2 x 640 ) / 640
= 2 / 640
= 2
Step3:
LCM(2, 869) = 1738
GCD(2, 869) = ( 2 x 869 ) / 1738
= 2 / 869
= 2
So, Greatest Common Divisor of 680, 826, 640, 869 is 1
