Given numbers are 870, 391, 603, 715
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(870, 391) = 340170
GCD(870, 391) = ( 870 x 391 ) / 340170
= 870 / 391
= 870
Step2:
LCM(1, 603) = 603
GCD(1, 603) = ( 1 x 603 ) / 603
= 1 / 603
= 1
Step3:
LCM(1, 715) = 715
GCD(1, 715) = ( 1 x 715 ) / 715
= 1 / 715
= 1
So, Greatest Common Divisor of 870, 391, 603, 715 is 1
