Given numbers are 560, 988, 457, 842
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(560, 988) = 138320
GCD(560, 988) = ( 560 x 988 ) / 138320
= 560 / 988
= 560
Step2:
LCM(4, 457) = 1828
GCD(4, 457) = ( 4 x 457 ) / 1828
= 4 / 457
= 4
Step3:
LCM(1, 842) = 842
GCD(1, 842) = ( 1 x 842 ) / 842
= 1 / 842
= 1
So, Greatest Common Divisor of 560, 988, 457, 842 is 1
