Given numbers are 820, 723, 392, 294
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 723) = 592860
GCD(820, 723) = ( 820 x 723 ) / 592860
= 820 / 723
= 820
Step2:
LCM(1, 392) = 392
GCD(1, 392) = ( 1 x 392 ) / 392
= 1 / 392
= 1
Step3:
LCM(1, 294) = 294
GCD(1, 294) = ( 1 x 294 ) / 294
= 1 / 294
= 1
So, Greatest Common Divisor of 820, 723, 392, 294 is 1
