Given numbers are 817, 778, 850, 140
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(817, 778) = 635626
GCD(817, 778) = ( 817 x 778 ) / 635626
= 817 / 778
= 817
Step2:
LCM(1, 850) = 850
GCD(1, 850) = ( 1 x 850 ) / 850
= 1 / 850
= 1
Step3:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
So, Greatest Common Divisor of 817, 778, 850, 140 is 1
