Given numbers are 320, 855, 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(320, 855) = 54720
GCD(320, 855) = ( 320 x 855 ) / 54720
= 320 / 855
= 320
Step2:
LCM(5, 247) = 1235
GCD(5, 247) = ( 5 x 247 ) / 1235
= 5 / 247
= 5
Step3:
LCM(1, 787) = 787
GCD(1, 787) = ( 1 x 787 ) / 787
= 1 / 787
= 1
So, Greatest Common Divisor of 320, 855, 247, 787 is 1
