GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(136, 980) = 33320
GCD(136, 980) = ( 136 x 980 ) / 33320
= 136 / 980
= 136
Step2:
LCM(4, 943) = 3772
GCD(4, 943) = ( 4 x 943 ) / 3772
= 4 / 943
= 4
Step3:
LCM(1, 689) = 689
GCD(1, 689) = ( 1 x 689 ) / 689
= 1 / 689
= 1
So, Greatest Common Divisor of 136, 980, 943, 689 is 1
