Given numbers are 121, 858, 154, 348
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(121, 858) = 9438
GCD(121, 858) = ( 121 x 858 ) / 9438
= 121 / 858
= 121
Step2:
LCM(11, 154) = 154
GCD(11, 154) = ( 11 x 154 ) / 154
= 11 / 154
= 11
Step3:
LCM(11, 348) = 3828
GCD(11, 348) = ( 11 x 348 ) / 3828
= 11 / 348
= 11
So, Greatest Common Divisor of 121, 858, 154, 348 is 1
