Given numbers are 428, 128, 475, 753
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 128) = 13696
GCD(428, 128) = ( 428 x 128 ) / 13696
= 428 / 128
= 428
Step2:
LCM(4, 475) = 1900
GCD(4, 475) = ( 4 x 475 ) / 1900
= 4 / 475
= 4
Step3:
LCM(1, 753) = 753
GCD(1, 753) = ( 1 x 753 ) / 753
= 1 / 753
= 1
So, Greatest Common Divisor of 428, 128, 475, 753 is 1
