Given numbers are 728, 980, 640, 347
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(728, 980) = 25480
GCD(728, 980) = ( 728 x 980 ) / 25480
= 728 / 980
= 728
Step2:
LCM(28, 640) = 4480
GCD(28, 640) = ( 28 x 640 ) / 4480
= 28 / 640
= 28
Step3:
LCM(4, 347) = 1388
GCD(4, 347) = ( 4 x 347 ) / 1388
= 4 / 347
= 4
So, Greatest Common Divisor of 728, 980, 640, 347 is 1
