Given numbers are 998, 658, 131, 211
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(998, 658) = 328342
GCD(998, 658) = ( 998 x 658 ) / 328342
= 998 / 658
= 998
Step2:
LCM(2, 131) = 262
GCD(2, 131) = ( 2 x 131 ) / 262
= 2 / 131
= 2
Step3:
LCM(1, 211) = 211
GCD(1, 211) = ( 1 x 211 ) / 211
= 1 / 211
= 1
So, Greatest Common Divisor of 998, 658, 131, 211 is 1
