Given numbers are 868, 455, 778, 247
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(868, 455) = 56420
GCD(868, 455) = ( 868 x 455 ) / 56420
= 868 / 455
= 868
Step2:
LCM(7, 778) = 5446
GCD(7, 778) = ( 7 x 778 ) / 5446
= 7 / 778
= 7
Step3:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
So, Greatest Common Divisor of 868, 455, 778, 247 is 1
