GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(858, 981) = 280566
GCD(858, 981) = ( 858 x 981 ) / 280566
= 858 / 981
= 858
Step2:
LCM(3, 315) = 315
GCD(3, 315) = ( 3 x 315 ) / 315
= 3 / 315
= 3
Step3:
LCM(3, 248) = 744
GCD(3, 248) = ( 3 x 248 ) / 744
= 3 / 248
= 3
So, Greatest Common Divisor of 858, 981, 315, 248 is 1
