Given numbers are 255, 410, 156, 102
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(255, 410) = 20910
GCD(255, 410) = ( 255 x 410 ) / 20910
= 255 / 410
= 255
Step2:
LCM(5, 156) = 780
GCD(5, 156) = ( 5 x 156 ) / 780
= 5 / 156
= 5
Step3:
LCM(1, 102) = 102
GCD(1, 102) = ( 1 x 102 ) / 102
= 1 / 102
= 1
So, Greatest Common Divisor of 255, 410, 156, 102 is 1
