Given numbers are 402, 280, 125, 709
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(402, 280) = 56280
GCD(402, 280) = ( 402 x 280 ) / 56280
= 402 / 280
= 402
Step2:
LCM(2, 125) = 250
GCD(2, 125) = ( 2 x 125 ) / 250
= 2 / 125
= 2
Step3:
LCM(1, 709) = 709
GCD(1, 709) = ( 1 x 709 ) / 709
= 1 / 709
= 1
So, Greatest Common Divisor of 402, 280, 125, 709 is 1
