Steps to Calculate GCD of 220, 685, 97, 807 using LCM Formula
Given numbers are 220, 685, 97, 807
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(220, 685) = 30140
GCD(220, 685) = ( 220 x 685 ) / 30140
= 220 / 685
= 220
Step2:
LCM(5, 97) = 485
GCD(5, 97) = ( 5 x 97 ) / 485
= 5 / 97
= 5
Step3:
LCM(1, 807) = 807
GCD(1, 807) = ( 1 x 807 ) / 807
= 1 / 807
= 1
So, Greatest Common Divisor of 220, 685, 97, 807 is 1
