Given numbers are 408, 780, 103, 822
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(408, 780) = 26520
GCD(408, 780) = ( 408 x 780 ) / 26520
= 408 / 780
= 408
Step2:
LCM(12, 103) = 1236
GCD(12, 103) = ( 12 x 103 ) / 1236
= 12 / 103
= 12
Step3:
LCM(1, 822) = 822
GCD(1, 822) = ( 1 x 822 ) / 822
= 1 / 822
= 1
So, Greatest Common Divisor of 408, 780, 103, 822 is 1
