Given numbers are 658, 250, 809, 831
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 250) = 82250
GCD(658, 250) = ( 658 x 250 ) / 82250
= 658 / 250
= 658
Step2:
LCM(2, 809) = 1618
GCD(2, 809) = ( 2 x 809 ) / 1618
= 2 / 809
= 2
Step3:
LCM(1, 831) = 831
GCD(1, 831) = ( 1 x 831 ) / 831
= 1 / 831
= 1
So, Greatest Common Divisor of 658, 250, 809, 831 is 1
