Given numbers are 868, 131, 519, 840
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(868, 131) = 113708
GCD(868, 131) = ( 868 x 131 ) / 113708
= 868 / 131
= 868
Step2:
LCM(1, 519) = 519
GCD(1, 519) = ( 1 x 519 ) / 519
= 1 / 519
= 1
Step3:
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
= 1 / 840
= 1
So, Greatest Common Divisor of 868, 131, 519, 840 is 1
