Steps to Calculate GCD of 355, 785, 222, 639 using LCM Formula

Given numbers are 355, 785, 222, 639

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

Apply this formula for all numbers.

Step1:

LCM(355, 785) = 55735

GCD(355, 785) = ( 355 x 785 ) / 55735

= 355 / 785

= 355


Step2:

LCM(5, 222) = 1110

GCD(5, 222) = ( 5 x 222 ) / 1110

= 5 / 222

= 5


Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1


So, Greatest Common Divisor of 355, 785, 222, 639 is 1
