Given numbers are 658, 114, 619, 308
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 114) = 37506
GCD(658, 114) = ( 658 x 114 ) / 37506
= 658 / 114
= 658
Step2:
LCM(2, 619) = 1238
GCD(2, 619) = ( 2 x 619 ) / 1238
= 2 / 619
= 2
Step3:
LCM(1, 308) = 308
GCD(1, 308) = ( 1 x 308 ) / 308
= 1 / 308
= 1
So, Greatest Common Divisor of 658, 114, 619, 308 is 1
