Given numbers are 870, 685, 233, 863
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 685) = 119190
GCD(870, 685) = ( 870 x 685 ) / 119190
= 870 / 685
= 870
Step2:
LCM(5, 233) = 1165
GCD(5, 233) = ( 5 x 233 ) / 1165
= 5 / 233
= 5
Step3:
LCM(1, 863) = 863
GCD(1, 863) = ( 1 x 863 ) / 863
= 1 / 863
= 1
So, Greatest Common Divisor of 870, 685, 233, 863 is 1
