Given numbers are 980, 142, 634, 655
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 142) = 69580
GCD(980, 142) = ( 980 x 142 ) / 69580
= 980 / 142
= 980
Step2:
LCM(2, 634) = 634
GCD(2, 634) = ( 2 x 634 ) / 634
= 2 / 634
= 2
Step3:
LCM(2, 655) = 1310
GCD(2, 655) = ( 2 x 655 ) / 1310
= 2 / 655
= 2
So, Greatest Common Divisor of 980, 142, 634, 655 is 1
