Given numbers are 787, 581, 678, 577
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(787, 581) = 457247
GCD(787, 581) = ( 787 x 581 ) / 457247
= 787 / 581
= 787
Step2:
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
= 1 / 678
= 1
Step3:
LCM(1, 577) = 577
GCD(1, 577) = ( 1 x 577 ) / 577
= 1 / 577
= 1
So, Greatest Common Divisor of 787, 581, 678, 577 is 1
