Given numbers are 472, 988, 647, 813
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(472, 988) = 116584
GCD(472, 988) = ( 472 x 988 ) / 116584
= 472 / 988
= 472
Step2:
LCM(4, 647) = 2588
GCD(4, 647) = ( 4 x 647 ) / 2588
= 4 / 647
= 4
Step3:
LCM(1, 813) = 813
GCD(1, 813) = ( 1 x 813 ) / 813
= 1 / 813
= 1
So, Greatest Common Divisor of 472, 988, 647, 813 is 1
