Given numbers are 257, 362, 780, 310
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(257, 362) = 93034
GCD(257, 362) = ( 257 x 362 ) / 93034
= 257 / 362
= 257
Step2:
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
= 1 / 780
= 1
Step3:
LCM(1, 310) = 310
GCD(1, 310) = ( 1 x 310 ) / 310
= 1 / 310
= 1
So, Greatest Common Divisor of 257, 362, 780, 310 is 1
