Given numbers are 344, 472, 647, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(344, 472) = 20296
GCD(344, 472) = ( 344 x 472 ) / 20296
= 344 / 472
= 344
Step2:
LCM(8, 647) = 5176
GCD(8, 647) = ( 8 x 647 ) / 5176
= 8 / 647
= 8
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 344, 472, 647, 781 is 1
