Given numbers are 842, 287, 780, 883
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(842, 287) = 241654
GCD(842, 287) = ( 842 x 287 ) / 241654
= 842 / 287
= 842
Step2:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
Step3:
LCM(1, 883) = 883
GCD(1, 883) = ( 1 x 883 ) / 883
= 1 / 883
= 1
So, Greatest Common Divisor of 842, 287, 780, 883 is 1
