Given numbers are 787, 102, 658, 309
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(787, 102) = 80274
GCD(787, 102) = ( 787 x 102 ) / 80274
= 787 / 102
= 787
Step2:
LCM(1, 658) = 658
GCD(1, 658) = ( 1 x 658 ) / 658
= 1 / 658
= 1
Step3:
LCM(1, 309) = 309
GCD(1, 309) = ( 1 x 309 ) / 309
= 1 / 309
= 1
So, Greatest Common Divisor of 787, 102, 658, 309 is 1
