Given numbers are 255, 783, 221, 889
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(255, 783) = 66555
GCD(255, 783) = ( 255 x 783 ) / 66555
= 255 / 783
= 255
Step2:
LCM(3, 221) = 663
GCD(3, 221) = ( 3 x 221 ) / 663
= 3 / 221
= 3
Step3:
LCM(1, 889) = 889
GCD(1, 889) = ( 1 x 889 ) / 889
= 1 / 889
= 1
So, Greatest Common Divisor of 255, 783, 221, 889 is 1
