Given numbers are 510, 785, 509, 981
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(510, 785) = 80070
GCD(510, 785) = ( 510 x 785 ) / 80070
= 510 / 785
= 510
Step2:
LCM(5, 509) = 2545
GCD(5, 509) = ( 5 x 509 ) / 2545
= 5 / 509
= 5
Step3:
LCM(1, 981) = 981
GCD(1, 981) = ( 1 x 981 ) / 981
= 1 / 981
= 1
So, Greatest Common Divisor of 510, 785, 509, 981 is 1
