Given numbers are 153, 655, 123, 787
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(153, 655) = 100215
GCD(153, 655) = ( 153 x 655 ) / 100215
= 153 / 655
= 153
Step2:
LCM(1, 123) = 123
GCD(1, 123) = ( 1 x 123 ) / 123
= 1 / 123
= 1
Step3:
LCM(1, 787) = 787
GCD(1, 787) = ( 1 x 787 ) / 787
= 1 / 787
= 1
So, Greatest Common Divisor of 153, 655, 123, 787 is 1
