Given numbers are 259, 511, 619, 840
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(259, 511) = 18907
GCD(259, 511) = ( 259 x 511 ) / 18907
= 259 / 511
= 259
Step2:
LCM(7, 619) = 4333
GCD(7, 619) = ( 7 x 619 ) / 4333
= 7 / 619
= 7
Step3:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
So, Greatest Common Divisor of 259, 511, 619, 840 is 1
