Given numbers are 681, 509, 143, 618
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(681, 509) = 346629
GCD(681, 509) = ( 681 x 509 ) / 346629
= 681 / 509
= 681
Step2:
LCM(1, 143) = 143
GCD(1, 143) = ( 1 x 143 ) / 143
= 1 / 143
= 1
Step3:
LCM(1, 618) = 618
GCD(1, 618) = ( 1 x 618 ) / 618
= 1 / 618
= 1
So, Greatest Common Divisor of 681, 509, 143, 618 is 1
