Given numbers are 851, 435, 489, 838
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(851, 435) = 370185
GCD(851, 435) = ( 851 x 435 ) / 370185
= 851 / 435
= 851
Step2:
LCM(1, 489) = 489
GCD(1, 489) = ( 1 x 489 ) / 489
= 1 / 489
= 1
Step3:
LCM(1, 838) = 838
GCD(1, 838) = ( 1 x 838 ) / 838
= 1 / 838
= 1
So, Greatest Common Divisor of 851, 435, 489, 838 is 1
