Given numbers are 720, 825, 247, 787
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(720, 825) = 39600
GCD(720, 825) = ( 720 x 825 ) / 39600
= 720 / 825
= 720
Step2:
LCM(15, 247) = 3705
GCD(15, 247) = ( 15 x 247 ) / 3705
= 15 / 247
= 15
Step3:
LCM(1, 787) = 787
GCD(1, 787) = ( 1 x 787 ) / 787
= 1 / 787
= 1
So, Greatest Common Divisor of 720, 825, 247, 787 is 1
