Given numbers are 980, 823, 784, 755
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 823) = 806540
GCD(980, 823) = ( 980 x 823 ) / 806540
= 980 / 823
= 980
Step2:
LCM(1, 784) = 784
GCD(1, 784) = ( 1 x 784 ) / 784
= 1 / 784
= 1
Step3:
LCM(1, 755) = 755
GCD(1, 755) = ( 1 x 755 ) / 755
= 1 / 755
= 1
So, Greatest Common Divisor of 980, 823, 784, 755 is 1
