Given numbers are 478, 900, 865, 784
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(478, 900) = 215100
GCD(478, 900) = ( 478 x 900 ) / 215100
= 478 / 900
= 478
Step2:
LCM(2, 865) = 1730
GCD(2, 865) = ( 2 x 865 ) / 1730
= 2 / 865
= 2
Step3:
LCM(1, 784) = 784
GCD(1, 784) = ( 1 x 784 ) / 784
= 1 / 784
= 1
So, Greatest Common Divisor of 478, 900, 865, 784 is 1
