Given numbers are 391, 802, 402, 776

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(391, 802) = 313582

GCD(391, 802) = ( 391 x 802 ) / 313582

= 391 / 802

= 391

Step2:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

Step3:

LCM(1, 776) = 776

GCD(1, 776) = ( 1 x 776 ) / 776

= 1 / 776

= 1

So, Greatest Common Divisor of 391, 802, 402, 776 is 1
