Given numbers are 784, 820, 760, 457
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 820) = 160720
GCD(784, 820) = ( 784 x 820 ) / 160720
= 784 / 820
= 784
Step2:
LCM(4, 760) = 760
GCD(4, 760) = ( 4 x 760 ) / 760
= 4 / 760
= 4
Step3:
LCM(4, 457) = 1828
GCD(4, 457) = ( 4 x 457 ) / 1828
= 4 / 457
= 4
So, Greatest Common Divisor of 784, 820, 760, 457 is 1
