Given numbers are 985, 715, 671, 405
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(985, 715) = 140855
GCD(985, 715) = ( 985 x 715 ) / 140855
= 985 / 715
= 985
Step2:
LCM(5, 671) = 3355
GCD(5, 671) = ( 5 x 671 ) / 3355
= 5 / 671
= 5
Step3:
LCM(1, 405) = 405
GCD(1, 405) = ( 1 x 405 ) / 405
= 1 / 405
= 1
So, Greatest Common Divisor of 985, 715, 671, 405 is 1
