Steps to Calculate GCD of 972, 781, 470, 247 using LCM Formula

Given numbers are 972, 781, 470, 247

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(972, 781) = 759132

GCD(972, 781) = ( 972 x 781 ) / 759132

= 972 / 781

= 972


Step2:

LCM(1, 470) = 470

GCD(1, 470) = ( 1 x 470 ) / 470

= 1 / 470

= 1


Step3:

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

= 1 / 247

= 1


So, Greatest Common Divisor of 972, 781, 470, 247 is 1
