Given numbers are 680, 905, 115, 141
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(680, 905) = 123080
GCD(680, 905) = ( 680 x 905 ) / 123080
= 680 / 905
= 680
Step2:
LCM(5, 115) = 115
GCD(5, 115) = ( 5 x 115 ) / 115
= 5 / 115
= 5
Step3:
LCM(5, 141) = 705
GCD(5, 141) = ( 5 x 141 ) / 705
= 5 / 141
= 5
So, Greatest Common Divisor of 680, 905, 115, 141 is 1
