Steps to Calculate GCD of 870, 391, 603, 715 using LCM Formula

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
