Steps to Calculate GCD of 434, 465, 770, 647 using LCM Formula

Given numbers are 434, 465, 770, 647

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

Apply this formula for all numbers.

Step1:

LCM(434, 465) = 6510

GCD(434, 465) = ( 434 x 465 ) / 6510

= 434 / 465

= 434


Step2:

LCM(31, 770) = 23870

GCD(31, 770) = ( 31 x 770 ) / 23870

= 31 / 770

= 31


Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1


So, Greatest Common Divisor of 434, 465, 770, 647 is 1
