Given numbers are 428, 900, 754, 409
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 900) = 96300
GCD(428, 900) = ( 428 x 900 ) / 96300
= 428 / 900
= 428
Step2:
LCM(4, 754) = 1508
GCD(4, 754) = ( 4 x 754 ) / 1508
= 4 / 754
= 4
Step3:
LCM(2, 409) = 818
GCD(2, 409) = ( 2 x 409 ) / 818
= 2 / 409
= 2
So, Greatest Common Divisor of 428, 900, 754, 409 is 1
