Given numbers are 159, 978, 214, 921
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(159, 978) = 51834
GCD(159, 978) = ( 159 x 978 ) / 51834
= 159 / 978
= 159
Step2:
LCM(3, 214) = 642
GCD(3, 214) = ( 3 x 214 ) / 642
= 3 / 214
= 3
Step3:
LCM(1, 921) = 921
GCD(1, 921) = ( 1 x 921 ) / 921
= 1 / 921
= 1
So, Greatest Common Divisor of 159, 978, 214, 921 is 1
