Steps to Calculate GCD of 445, 431, 70, 356 using LCM Formula
Given numbers are 445, 431, 70, 356
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(445, 431) = 191795
GCD(445, 431) = ( 445 x 431 ) / 191795
= 445 / 431
= 445
Step2:
LCM(1, 70) = 70
GCD(1, 70) = ( 1 x 70 ) / 70
= 1 / 70
= 1
Step3:
LCM(1, 356) = 356
GCD(1, 356) = ( 1 x 356 ) / 356
= 1 / 356
= 1
So, Greatest Common Divisor of 445, 431, 70, 356 is 1
