Given numbers are 623, 398, 932, 780

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

Apply this formula for all numbers.

Step1:

LCM(623, 398) = 247954

GCD(623, 398) = ( 623 x 398 ) / 247954

= 623 / 398

= 623

Step2:

LCM(1, 932) = 932

GCD(1, 932) = ( 1 x 932 ) / 932

= 1 / 932

= 1

Step3:

LCM(1, 780) = 780

GCD(1, 780) = ( 1 x 780 ) / 780

= 1 / 780

= 1

So, Greatest Common Divisor of 623, 398, 932, 780 is 1
