Given numbers are 428, 825, 781, 803
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 825) = 353100
GCD(428, 825) = ( 428 x 825 ) / 353100
= 428 / 825
= 428
Step2:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
Step3:
LCM(1, 803) = 803
GCD(1, 803) = ( 1 x 803 ) / 803
= 1 / 803
= 1
So, Greatest Common Divisor of 428, 825, 781, 803 is 1
