Given numbers are 840, 420, 929, 302
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 420) = 840
GCD(840, 420) = ( 840 x 420 ) / 840
= 840 / 420
= 840
Step2:
LCM(420, 929) = 390180
GCD(420, 929) = ( 420 x 929 ) / 390180
= 420 / 929
= 420
Step3:
LCM(1, 302) = 302
GCD(1, 302) = ( 1 x 302 ) / 302
= 1 / 302
= 1
So, Greatest Common Divisor of 840, 420, 929, 302 is 1
