Given numbers are 428, 380, 232, 105
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 380) = 40660
GCD(428, 380) = ( 428 x 380 ) / 40660
= 428 / 380
= 428
Step2:
LCM(4, 232) = 232
GCD(4, 232) = ( 4 x 232 ) / 232
= 4 / 232
= 4
Step3:
LCM(4, 105) = 420
GCD(4, 105) = ( 4 x 105 ) / 420
= 4 / 105
= 4
So, Greatest Common Divisor of 428, 380, 232, 105 is 1
