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
