Given numbers are 690, 255, 93, 863
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 255) = 11730
GCD(690, 255) = ( 690 x 255 ) / 11730
= 690 / 255
= 690
Step2:
LCM(15, 93) = 465
GCD(15, 93) = ( 15 x 93 ) / 465
= 15 / 93
= 15
Step3:
LCM(3, 863) = 2589
GCD(3, 863) = ( 3 x 863 ) / 2589
= 3 / 863
= 3
So, Greatest Common Divisor of 690, 255, 93, 863 is 1
