Given numbers are 780, 820, 864, 906
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(780, 820) = 31980
GCD(780, 820) = ( 780 x 820 ) / 31980
= 780 / 820
= 780
Step2:
LCM(20, 864) = 4320
GCD(20, 864) = ( 20 x 864 ) / 4320
= 20 / 864
= 20
Step3:
LCM(4, 906) = 1812
GCD(4, 906) = ( 4 x 906 ) / 1812
= 4 / 906
= 4
So, Greatest Common Divisor of 780, 820, 864, 906 is 2
