GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(855, 792) = 75240
GCD(855, 792) = ( 855 x 792 ) / 75240
= 855 / 792
= 855
Step2:
LCM(9, 755) = 6795
GCD(9, 755) = ( 9 x 755 ) / 6795
= 9 / 755
= 9
Step3:
LCM(1, 258) = 258
GCD(1, 258) = ( 1 x 258 ) / 258
= 1 / 258
= 1
So, Greatest Common Divisor of 855, 792, 755, 258 is 1
