Given numbers are 239, 478, 840, 678
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(239, 478) = 478
GCD(239, 478) = ( 239 x 478 ) / 478
= 239 / 478
= 239
Step2:
LCM(239, 840) = 200760
GCD(239, 840) = ( 239 x 840 ) / 200760
= 239 / 840
= 239
Step3:
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
= 1 / 678
= 1
So, Greatest Common Divisor of 239, 478, 840, 678 is 1
