Given numbers are 320, 398, 784, 681
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(320, 398) = 63680
GCD(320, 398) = ( 320 x 398 ) / 63680
= 320 / 398
= 320
Step2:
LCM(2, 784) = 784
GCD(2, 784) = ( 2 x 784 ) / 784
= 2 / 784
= 2
Step3:
LCM(2, 681) = 1362
GCD(2, 681) = ( 2 x 681 ) / 1362
= 2 / 681
= 2
So, Greatest Common Divisor of 320, 398, 784, 681 is 1
