Given numbers are 842, 453, 870, 457
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(842, 453) = 381426
GCD(842, 453) = ( 842 x 453 ) / 381426
= 842 / 453
= 842
Step2:
LCM(1, 870) = 870
GCD(1, 870) = ( 1 x 870 ) / 870
= 1 / 870
= 1
Step3:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
So, Greatest Common Divisor of 842, 453, 870, 457 is 1
