GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(783, 861) = 224721
GCD(783, 861) = ( 783 x 861 ) / 224721
= 783 / 861
= 783
Step2:
LCM(3, 975) = 975
GCD(3, 975) = ( 3 x 975 ) / 975
= 3 / 975
= 3
Step3:
LCM(3, 247) = 741
GCD(3, 247) = ( 3 x 247 ) / 741
= 3 / 247
= 3
So, Greatest Common Divisor of 783, 861, 975, 247 is 1
