Steps to Calculate GCD of 247, 393, 751, 785 using LCM Formula

Given numbers are 247, 393, 751, 785

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

Apply this formula for all numbers.

Step1:

LCM(247, 393) = 97071

GCD(247, 393) = ( 247 x 393 ) / 97071

= 247 / 393

= 247


Step2:

LCM(1, 751) = 751

GCD(1, 751) = ( 1 x 751 ) / 751

= 1 / 751

= 1


Step3:

LCM(1, 785) = 785

GCD(1, 785) = ( 1 x 785 ) / 785

= 1 / 785

= 1


So, Greatest Common Divisor of 247, 393, 751, 785 is 1
