Given numbers are 693, 222, 436, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(693, 222) = 51282
GCD(693, 222) = ( 693 x 222 ) / 51282
= 693 / 222
= 693
Step2:
LCM(3, 436) = 1308
GCD(3, 436) = ( 3 x 436 ) / 1308
= 3 / 436
= 3
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 693, 222, 436, 220 is 1
