Given numbers are 550, 781, 921, 125
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(550, 781) = 39050
GCD(550, 781) = ( 550 x 781 ) / 39050
= 550 / 781
= 550
Step2:
LCM(11, 921) = 10131
GCD(11, 921) = ( 11 x 921 ) / 10131
= 11 / 921
= 11
Step3:
LCM(1, 125) = 125
GCD(1, 125) = ( 1 x 125 ) / 125
= 1 / 125
= 1
So, Greatest Common Divisor of 550, 781, 921, 125 is 1
