Given numbers are 198, 634, 390, 841
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(198, 634) = 62766
GCD(198, 634) = ( 198 x 634 ) / 62766
= 198 / 634
= 198
Step2:
LCM(2, 390) = 390
GCD(2, 390) = ( 2 x 390 ) / 390
= 2 / 390
= 2
Step3:
LCM(2, 841) = 1682
GCD(2, 841) = ( 2 x 841 ) / 1682
= 2 / 841
= 2
So, Greatest Common Divisor of 198, 634, 390, 841 is 1
