Given numbers are 980, 208, 841, 124
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 208) = 50960
GCD(980, 208) = ( 980 x 208 ) / 50960
= 980 / 208
= 980
Step2:
LCM(4, 841) = 3364
GCD(4, 841) = ( 4 x 841 ) / 3364
= 4 / 841
= 4
Step3:
LCM(1, 124) = 124
GCD(1, 124) = ( 1 x 124 ) / 124
= 1 / 124
= 1
So, Greatest Common Divisor of 980, 208, 841, 124 is 1
