Given numbers are 798, 218, 148, 255
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(798, 218) = 86982
GCD(798, 218) = ( 798 x 218 ) / 86982
= 798 / 218
= 798
Step2:
LCM(2, 148) = 148
GCD(2, 148) = ( 2 x 148 ) / 148
= 2 / 148
= 2
Step3:
LCM(2, 255) = 510
GCD(2, 255) = ( 2 x 255 ) / 510
= 2 / 255
= 2
So, Greatest Common Divisor of 798, 218, 148, 255 is 1
