Given numbers are 420, 944, 766, 605
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 944) = 99120
GCD(420, 944) = ( 420 x 944 ) / 99120
= 420 / 944
= 420
Step2:
LCM(4, 766) = 1532
GCD(4, 766) = ( 4 x 766 ) / 1532
= 4 / 766
= 4
Step3:
LCM(2, 605) = 1210
GCD(2, 605) = ( 2 x 605 ) / 1210
= 2 / 605
= 2
So, Greatest Common Divisor of 420, 944, 766, 605 is 1
