GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(247, 804) = 198588
GCD(247, 804) = ( 247 x 804 ) / 198588
= 247 / 804
= 247
Step2:
LCM(1, 794) = 794
GCD(1, 794) = ( 1 x 794 ) / 794
= 1 / 794
= 1
Step3:
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
= 1 / 640
= 1
So, Greatest Common Divisor of 247, 804, 794, 640 is 1
