Given numbers are 784, 804, 645, 318
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(784, 804) = 157584
GCD(784, 804) = ( 784 x 804 ) / 157584
= 784 / 804
= 784
Step2:
LCM(4, 645) = 2580
GCD(4, 645) = ( 4 x 645 ) / 2580
= 4 / 645
= 4
Step3:
LCM(1, 318) = 318
GCD(1, 318) = ( 1 x 318 ) / 318
= 1 / 318
= 1
So, Greatest Common Divisor of 784, 804, 645, 318 is 1
