Given numbers are 121, 396, 902, 430
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(121, 396) = 4356
GCD(121, 396) = ( 121 x 396 ) / 4356
= 121 / 396
= 121
Step2:
LCM(11, 902) = 902
GCD(11, 902) = ( 11 x 902 ) / 902
= 11 / 902
= 11
Step3:
LCM(11, 430) = 4730
GCD(11, 430) = ( 11 x 430 ) / 4730
= 11 / 430
= 11
So, Greatest Common Divisor of 121, 396, 902, 430 is 1
