Given numbers are 142, 980, 804, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(142, 980) = 69580
GCD(142, 980) = ( 142 x 980 ) / 69580
= 142 / 980
= 142
Step2:
LCM(2, 804) = 804
GCD(2, 804) = ( 2 x 804 ) / 804
= 2 / 804
= 2
Step3:
LCM(2, 649) = 1298
GCD(2, 649) = ( 2 x 649 ) / 1298
= 2 / 649
= 2
So, Greatest Common Divisor of 142, 980, 804, 649 is 1
