GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(550, 842) = 231550
GCD(550, 842) = ( 550 x 842 ) / 231550
= 550 / 842
= 550
Step2:
LCM(2, 719) = 1438
GCD(2, 719) = ( 2 x 719 ) / 1438
= 2 / 719
= 2
Step3:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
So, Greatest Common Divisor of 550, 842, 719, 405 is 1
