Given numbers are 159, 465, 390, 820
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(159, 465) = 24645
GCD(159, 465) = ( 159 x 465 ) / 24645
= 159 / 465
= 159
Step2:
LCM(3, 390) = 390
GCD(3, 390) = ( 3 x 390 ) / 390
= 3 / 390
= 3
Step3:
LCM(3, 820) = 2460
GCD(3, 820) = ( 3 x 820 ) / 2460
= 3 / 820
= 3
So, Greatest Common Divisor of 159, 465, 390, 820 is 1
