Given numbers are 220, 428, 862, 919
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 428) = 23540
GCD(220, 428) = ( 220 x 428 ) / 23540
= 220 / 428
= 220
Step2:
LCM(4, 862) = 1724
GCD(4, 862) = ( 4 x 862 ) / 1724
= 4 / 862
= 4
Step3:
LCM(2, 919) = 1838
GCD(2, 919) = ( 2 x 919 ) / 1838
= 2 / 919
= 2
So, Greatest Common Divisor of 220, 428, 862, 919 is 1
